Bone Char is a granular material produced by charring bovine bones: the bones are heated to high temperatures (in the range of 400 to 500 °C), and a unique form of activated carbon is created. Bone char consists mainly of calcium phosphate (Ca₃(PO₄)₂), Calcium Carbonate (CaCO₃), and a small amount of carbon (~12%); however, the quality of the bone chars is controlled by the amount of oxygen present in the charring atmosphere. Bone chars usually have a lower surface area than activated carbons but present high adsorptive capacities for copper, zinc, and cadmium. The carbonized material possesses great mechanical strength and improved adsorption of many chemicals, e.g., Fluorine, Chlorine, Lead, and many more.

Copper Phosphorus (CuP) Alloy is an alloy made from copper being deoxidized with phosphorus. This is the most commonly used deoxidized copper. This master alloy is used as a deoxidant and alloying agent in the copper industry and also has applications in the aluminum, bronze, and brass industry. Copper is corrosion-resistant, but this property becomes enhanced with added phosphor. There is an increase in tensile strength, a reduction in brittleness characteristics, and an improvement in machinability and workability with the phosphorus addition to copper. Reade offers one grade for the aluminum industry and three grades for the copper industry.

Diatomaceous earth, also known as Diatomaceous silica (SiO₂*nH₂O), is the fossilized remains of tiny, aquatic organisms called diatoms that have accumulated, creating silica deposits. DE has high absorption, low bulk density, and high brightness. There are two primary types of diatomaceous earth deposits - saltwater and freshwater. Saltwater DE is commercially processed in the United States and primarily used as a filter aid. Freshwater DE is ideal for agricultural uses because it typically has a low crystalline silica content (amorphous), is highly absorptive, and is an ancient pest control agent. As awareness of and concern about chemical pesticides grow, diatomaceous earth has increased interest as a non-toxic and natural alternative. It is also seen as a natural anti-parasitic by farmers and ranchers.

Mg-AL Alloys with high amounts of magnesium (around 50%) are brittle and more susceptible to corrosion than aluminum making them unsuitable for most engineering uses. These alloys are flammable when powdered, are more resistant to corrosion than pure magnesium, and are more reactive than pure aluminum, making them useful for pyrotechnics as a metal fuel and to produce sparks. The brittleness of the alloy makes it easily broken by a hammer and ground into usable powder, which is beneficial for pyrotechnics. Magnesium Aluminum powder is a silver-gray solid metallic powder.

Magnesium (Mg) Powder is a light, moderately hard, silvery-white metal that ignites easily in the air and burns with a bright light. It is strong, has good heat dissipation and dampening, and is easy to weld, forge, cast or machine.

How hydraulic, automotive, and aerospace application components perform when exposed to particles of sand and dust is essential during use as well as lifetime durability and performance. Sand and dust test standards address environmental conditions that materials and products may face during operation so contamination by solid particles can be controlled. These standard reference materials have been designed to improve precision and accuracy in particle counting.

Zeolites are hydrated aluminosilicate minerals that contain exchangeable alkali and alkaline metals. They can be natural or synthetic. They are characterized by a framework structure that encloses interconnected cavities occupied by ion-exchangeable large metal cations and water molecules, permitting ion exchange and reversible dehydration.

They have pore structures, which create large effective surface areas, which gives them superior adsorptive and filtration qualities. They also have adjustable acidities, are thermally stable, and are reusable, making them active in various reactions.

Zero-Valent Iron (ZVI / NZVI / EZVI) is a form of elemental iron that reduces inorganic ions in water because ZVI is fairly reactive in water and can serve as an excellent electron donor. Zero-valent iron (ZVI) has been successfully used for the degradation of a wide range of organic contaminants in groundwaters in recent years, including selenium (Se), arsenic (As), lead (Pb), and mercury (Hg), and many other pollutants. The rate of degradation of contaminants may be enhanced by the use of nanoscale zero-valent iron (nZVI) particles which possess higher surface area than the more widely used granular materials. nZVI can also be used to create Emulsified Zero-valent Iron for groundwater treatment.
