Whether it’s in protective structures or microns-thin films, magnetite plays an important role in preventing workplace exposure to harmful radiation

It’s no secret that radiation can save lives and improve healthcare. Just consider the necessity of an X-ray to repair that fractured wrist or the effectiveness of radiation treatments on certain cancers.

Prolonged exposure to this life-saving radiation, though, can prove harmful — especially to the caregivers tasked with providing care. When it comes to protecting employees from the harmful effects of radiation in the workplace or excess heat in a refractory, Quality Magnetite is on the forefront.

“Our magnetite can be used in concrete aggregate, into building products and into surface coatings for protection against the harmful effects of radiation and heat,” says QMag. “We understand the importance of providing a high-quality iron oxide for these vital applications.”

When it comes to providing protective barriers, research is beginning to show that magnetite-rich compounds and products are a cost-effective way to limit exposure and provide the protection employees need. Here are a few points to consider:

Magnetite in concrete is an affordable and effective gamma-ray blocker. Researchers have known for some time that magnetite can be an effective shield against harmful gamma rays. At the same time, concrete is one of the most affordable and proven construction materials available. Recent developments have demonstrated that magnetite, combined with concrete aggregate, is as effective at blocking harmful gamma rays as lead bricks — and it’s far cheaper.

Magnetite is an effective additive for radiation-blocking plastics. The need for thinner, flexible protective barriers has been apparent for decades, and researchers have been pursuing everything from thinner, woven lead vests to fabrics infused with particles to absorb harmful gamma rays. One of the most promising areas of progress has been in the polymer arena, where the Society of Plastics Engineers (SPE) reports that researchers are adding magnetite nanoparticles to plastic films as a form of gamma ray blocker. Here’s what SPE had to say about these cutting-edge films:


They are lighter than their metal counterparts and can be processed to achieve effective shielding for radiation associated with specific industries. They also combine the excellent functional properties of the nanoparticles with those of the host polymers. Incorporating even just a few percent of nanoparticles can dramatically change the properties.1

Magnetite-infused concrete is an effective heatsink. For centuries, concrete has been used as an effective barrier to heat. Now, thanks to researchers at Hanyang University, concrete is being examined as an effective conduit for the removal of excess heat. Researchers at Hanyang discovered that, by infusing concrete aggregate with high percentages of magnetite, the wonder material can be an effective heat transfer conduit — without the effects of cracking typical to concrete placed in high-heat situations. Here’s what they found:


For the work, magnetite with varying replacements of normal aggregates and steel powder of 1.5% of volume are considered, and the equivalent thermal conductivity is evaluated. Only when the replacement ratio goes up to 30%, thermal conductivity increases rapidly to 2.5 times.2

This bold application of magnetite has staggering implications in construction of refractories, industrial complexes and even nuclear reactors. When coupled with the radiological protections of similar products, magnetite and concrete is a winning combination.

Quality Magnetite Can Help Make a Great Paint

March 13, 2017 / Newsroom
Magnetite in Paint Products

Magnetite additives enrich environmentally friendly anticorrosive paints and richer pigments

When it comes to paints and pigments, goals sometimes conflict. Paints need to improve the lifespan and durability of a surface, protecting it from harsh elements, and they also need to beautify surfaces and provide for pleasing aesthetics.

At Quality Magnetite, we’re on the forefront of providing a high-quality magnetite product to paint and pigment producers in order to help them develop richer, deeper colors and stronger, more effective protective surfaces. More importantly, our magnetite can help realize both goals in an environmentally friendly manner than traditional chemical processes.

“Magnetite is a tremendous additive for paints and pigments, and we’re a great source for the quality of product that manufacturers need,” says Bud May, Quality Magnetite VP. “Our customers rely on our products for quality, consistency and speed of delivery, and we’re excited to be exploring the emerging field of magnetite paint and pigments.”

Researchers around the globe are recognizing the benefits of magnetite to the paint and pigment production process. Here are just a few ways Quality Magnetite can help improve the process of making more durable paints and more vibrant pigments.

Particle size drives effectiveness of ‘doping’ elements

Researchers at the University of Antioch in Columbia examined the process of “doping” magnetite-enriched paints and pigments — a technique in which cadmium, copper or other metals are introduced during the manufacturing process to improve both richness of colors and a paint’s anticorrosive properties. As they examined the various techniques, researchers made a discovery.

“The particle size of magnetite pigments depends on the nature and quantity of the doping element,” the researchers reveal. “The synthesis procedure adopted resulted in pigments with particle sizes similar to micronized industrial particle sizes.”

Using a more consistent, smaller-sized magnetite particle like those produced by Quality Magnetite resulted in stronger surfaces, more durable anticorrosive properties and deeper, richer colors. At the same time, other researchers are finding that magnetite-enriched paints and pigments are more environmentally friendly.

An ancient process reduces environmental impacts of paints and pigments

If you’ve ever seen pottery from ancient cultures in North or South America, then you’ve seen a magnetite-based pigment. The process of using magnetite to create vibrant, durable colors is hardly new. What researchers are finding, though, is that magnetite-infused coatings are revolutionizing protective surfacing, especially where it counts — in marine environments.

The Royal Society of Chemistry recently published a report that outlined the power that magnetite-rich epoxy coatings have to protect steel in marine settings. Not only did magnetite help build better, less toxic coatings, but it also led to coatings that were surprisingly resilient and in many instances self-healing when damaged.

“The mechanism of self-healing characteristics of porous nanomaterials was elucidated using different analyses,” researchers stated. “The results suggested the formation of stable thin films on the cracks and holes of epoxy coats.”

The development of more environmentally-friendly self-healing coatings is an innovative and emerging field that Quality Magnetite is excited to play a small part in. As with many industrial applications, the consistency and quality of iron oxide seems to be a key element, and at Quality Magnetite, we specialize in processes and techniques that produce the highest quality most consistently.

Magnetite in Sporting Equipment

From football to bowling, Quality Magnetite products play an important role in athletics

You’ve probably seen the bracelets on wrists of football players — tiny disks of magnets that help improve circulation and restore freedom of movement to tight joints. At Quality Magnetite, it’s not just about magnets. Our products are an important component in many cutting edge sports.

“QMag works to stay abreast of changes in more than 80 industries — medical, construction, and even sports, where our products find their way into hundreds of products,” says George Hamilton, QMag Operations Manager. “We’re sports lovers, and knowing our products are a part of those sports we love makes us proud of what we do.”

Here are a few interesting and unexpected places you’ll find magnetite produced right here at QMag.

Bowling balls: Bowling balls are round, three holes for your fingers, and smooth, right? What you can’t see is that magnetite is an important component to making those balls curve, backspin and cut. Look inside a bowling ball, and you’ll find they’re filled with aggregates, shaped and molded to behave in certain ways. Without magnetite, the bowling balls wouldn’t be heavy enough to perform as expected. Magnetite provides mass where it’s needed and gives the balls the performance bowlers demand.

Golf clubs: For more than a decade, golf clubs have been getting lighter. Yet, reducing weight can’t reduce strength of the club. That’s why magnetite is one of the main ingredients in the alloys that manufacturers are using to achieve stronger, lighter clubs. When Tiger steps on the field, he can crush it with confidence, knowing his clubs will perform consistently under a variety of conditions, thanks in part to iron oxide.

Roller hockey skates: You’ve seen the skaters gliding effortlessly around the floor, knocking the puck about and scoring big wins. The skaters cut sideways and for just a second, the skates hum. That signature hum is thanks in no small part to magnetite — a crucial component of quality ball bearings. Those ball bearings help make sure that the skaters’ kicks perform well under pressure, and without quality iron ore, those ball bearings would break down and freeze up.

There are thousands of products, processes and technologies in the sporting goods arena where you’ll find iron oxide in all its forms. At QMag, we specialize in providing the highest quality in the fastest possible timetables, so that your business can remain ahead of the competition.

Magnetite for Agriculture

Research shows iron oxide particles play a key role in improving crop yield and quality

Iron-rich compounds have long been a key component of successful agricultural development, and now, magnetite is leading the way to improved crop yields as farmers reduce — and even eliminate — harmful pesticide residues. As a leader in the magnetite industry, Quality Magnetite is a reliable source for high-quality ferro-particles for use in agricultural products across a host of crops.

The National Institutes of Health recently revealed that researchers in China have demonstrated iron oxide (Fe304) improves the availability of iron to peanut plants, reducing the need for additional fertilizers, which typically leach out of the sandy soils in which the plants thrive. Quality Magnetite is skilled at producing the kinds of iron-rich compounds farmers need to reduce pesticide and fertilizer use while enhancing crop yields.

Here are a couple of areas in which researchers are exploring the use of magnetic nanoparticles in agriculture.

Iron may speed the degradation of old, dangerous pesticides

The pesticide DDT has long been banned for use on agricultural products. Yet, decades later, residues of the chemical linger in soils. Writing in the journal Chemosphere, scientists noted that iron oxide shows a remarkable tendency to speed the breakdown of DDT.

Over time, the iron aids in breaking down the chemical and spiriting it away, restoring the soil to healthy and productive use. When coupled with other soil quality remediation techniques, iron can restore contaminated farm lands faster than other natural means, all without harming vital water sources.

Magnetite shown to improve soybean yields

Soybeans represent a $35 billion slice of the American agriculture industry, and production of this vital staple food has increased 15-fold since the 1950s. Recent research explored the effects of adding small amounts of magnetite nanoparticles to soils during the production of this important plant.

“It seems that the use of iron particles causes increasing pod and dry leaf weight and finally will increase total yield,” writes the lead scientist in the study, which was published in 2010 in Notulae Scientia Biologicae, an international journal of science.

As further research on these and other exciting findings continues, the use for magnetite in agriculture and soil remediation will continue to grow.

Quality Magnetite Exploring Nano-Particle Medical Markets

January 6, 2017 / Newsroom
Magnetite in Nano-Particle Medical Markets

Equipment advances will enable the creation of smaller, uniform magnetite particles

Quality Magnetite is poised at the forefront of an exciting and revolutionary new field of medical research and treatment. Magnetic Resonance Imaging — or MRI — is one of the most remarkable medical imaging tools ever created, and researchers believe that magnetite nanoparticles could take MRI to even greater heights.

By employing iron oxide nanoparticles as contrast agents, scientists anticipate using MRI to reveal the very shapes of cancer cells themselves. For these advances to become reality, ferrous oxide (FeO) particles must be uniform and incredibly small, which requires specialized equipment and cutting-edge manufacturing and quality control techniques. Quality Magnetite is keeping a close eye on the medical imaging industry as we consider this explosive new field of research.

“Right now, these techniques are still in the testing phase, but that could change at any moment,” says Quality Magnetite Operations Manager George Hamilton. “As one of the premier sources for quality, refined magnetite, we’re well-positioned to become a major provider of ferrous nanoparticles for medical imaging and contrast.”

Researchers have identified some of the benefits of magnetite for MRI, and as the science behind this emerging technology develops, here are just a few of the reasons these innovations are worth watching.

Magnetite imaging contrasts improve accuracy and detail

MRI machines use powerful magnetic fields to discern the subtle differences among tissue density, which allows radiologists to explore tiny slices of an individual’s anatomy, looking for everything from aneurysms to tumors. The paramagnetic properties of ferrous materials can improve the resolution of MRI machines because of the material’s unique properties and density.

Through the manufacture of high quality, uniform and uniquely shaped particles, scientists believe that magnetite will allow them to explore the shapes of tumors, improving radiation and chemotherapy treatments or allowing for more effective surgical solutions to invasive cancers. Also, because of some iron compounds’ unique interactions with certain compounds in blood and tissues, these ferro-particles may allow radiologists to diagnose and describe vascular conditions in much greater detail than ever before.

Biodegradable and biologically safe compounds decrease need for potentially toxic radiological or dye-based contrast agents

Current state-of-the-art contrast agents utilize potentially harmful substances, such as dyes and radioactive tracer elements, to improve resolution in MRI images and bring out hidden structures. Certain ferrous nanoparticles are biodegradable, however, and these tiny particles can be designed to move more freely throughout structures of the body.

Researchers believe these tiny compounds can one day be used to successfully diagnose and treat a host of cardiovascular and even neurological conditions, reducing or even eliminating the need for radioactive tracers and heavy, potentially toxic dyes. Magnetite nanoparticles are at the forefront of an amazing new frontier for medical imaging, and Quality Magnetite will be there to supply this need.

Magnetite in Aviation

From electronics to aviation, the future is bright for magnetite

At Quality Magnetite, we’re constantly watching for exciting and new uses of magnetite, whether it’s refinements in process technologies that have long relied on magnetite or discovering innovative ways magnetite can open up new markets and industries.

With the nano-revolution well underway, the demand for ferro-particles will increase in the coming years. That means finding and securing a reliable source for this finite resource is a vital step for companies and manufacturers who wish to remain on the forefront of technology.

“Magnetite plays a role in almost every major industry,” says Quality Magnetite Operations Manager George Hamilton. “From agriculture to the tech boom, magnetite is a key component of machinery, chemical manufacturing, monitoring and even heat abatement. And with the nano-scale applications of this material, the importance of magnetite will continue to grow in the coming years.”

Here are just three of the hundreds of areas in which magnetite is playing a major role in progress.

Electronics components rely on magnetite. Almost every computer on the market requires magnetite to work. Whether it’s embedded in state-of-the-art chips or applied to microscopic moving parts, magnetite helps keep computers working and, without it, the electronics revolution would grind to a halt.

Magnetite helps control pollution. Renewable energy is on the rise, but for the immediate future, fossil fuels still reign supreme. Coal accounts for almost 40% of the electricity produced in the U.S. each year. Thanks to closed-loop processes made possible by magnetite, though, energy producers are reducing harmful emissions.

Ferrofluids reduce vibration and control sound. Magnetic ferrofluids are revolutionizing mechanical systems, thanks to their unique abilities to dampen vibration and reduce unwanted sound. From helicopters to buildings, engineers are employing ferrofluids to control unwanted vibrations from rotors and protect structures from earthquakes.

Magnetite is an ancient material, but it’s still on the forefront of almost every industry, and at Quality Magnetite, we’re looking to the future. From medicine to space propulsion systems, when it comes to magnetite, even the sky isn’t the limit.

How ferrofluids work

November 13, 2016 / Videos

Ferrofluids are made up of tiny magnetic fragments of iron suspended in kerosene or oil with a surfactant to prevent them from clumping. Although expensive to buy online, you can make ferrofluid easily and cheaply at home.

From speakers to computer hard drives, there are many ways ferrofluids are used commercially. The oily fluid prevents debris from entering hard drives when a small amount is placed between the magnets and shaft. In the case of speakers ferrofluids remove heat from the voice coils and help dampen the cone movement. Ferrofluids can be used to help make dynamic molds by pouring a hardening agent over the fluids.
