Ammonium perchlorate is a white, odorless, crystalline powder with the chemical formula NH₄ClO₄. It is a powerful oxidizer that can readily provide oxygen to support combustion. Ammonium perchlorate is stable under normal conditions; however, proper safety measures should be taken when working with ammonium perchlorate as it can react violently with certain chemicals, and its dust can be explosive. Reade offers ammonium perchlorate in three granulations and per MIL-A-192B. Custom granulations down to 50 microns are available upon request. Typical Assay as NH₄ClO₄: 98.8% Min.

Antimony(III) Sulfide (Sb₂S₃), or Antimony Trisulfide, is the most common antimony mineral and the chief source of the metal. It is a black needle-like crystal and semiconductor with a direct band gap of 1.8–2.5 eV. Purity: 98.0% up to 99.99% Powder sized down to nanometers

Beryllium oxide (BeO), also known as beryllia, is an inorganic compound that is a white crystalline solid and has a unique combination of thermal, electrical, optical, and mechanical properties. Beryllia is an electrical insulator and an excellent thermal conductor, with conductivity higher than any other non-metal except diamond and many metals. It is an ideal material for applications requiring large heat dissipation and dielectric and mechanical strength. Beryllia’s high melting point leads to its use as a refractory material.

Note: Beryllium oxide is toxic; beryllium oxide ceramics are not toxic.

Available purity 99.5%, 99.7%, and 99.98% trace metals basis

Black Nickel Oxide, Nickel(III) Oxide (Ni₂O₃), is a powerful and refractory colorant that can produce gray, blue and yellow. It has a high surface area and high chemical reactivity.

Calcite is the most common form of calcium carbonate (CaCO₃). It is a common mineral and a major constituent of limestone and marble. Calcite is an inexpensive crushed and screened white marble media that can be used to neutralize acidic or low pH waters to a neutral, less corrosive effluent. Highly variable in form and color, calcite is best recognized by its relatively low hardness (H = 3) and its high reactivity with even weak acids, such as vinegar. When acidic water reaches neutral pH, no more calcite is dissolved.

Calcium Carbonate Ca(CO₃) is a common substance found in rock and is the main component of shells of marine organisms, snails, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural lime. It is produced by crushing, grinding, precipitation, and classifying high purity, white calcite limestone. Purities available from 98% to 99.9%

Cerium(IV) oxide, or cerium dioxide, usually appears as a yellow powder that is insoluble in water and moderately soluble in strong mineral acids. Cerium oxide is slightly hygroscopic and will absorb small amounts of moisture and CO2 from the atmosphere. Purities are available from 98% (industrial grade) to 99.999% (high purity grade).

This aluminum oxide is a virgin fused white aluminum oxide. It is friable, high purity, medium density, and abrasive.

FerroPhosphorus is an alloy of iron and phosphorus. This ferroalloy contains high proportions of Iron Phosphides, Fe₂P, and Fe₃P. Ferrophosphorus is used in many industrial applications, and it is becoming increasingly popular in the manufacture of steel as the addition of it increases the steel's corrosion resistance and strength. It also works as a deoxidizing agent. Ferrophosphorus enhances molten iron's fluidity, improving iron alloys' casting performance.

Forsterite is a crystalline Magnesium Silicate (Mg₂(SiO₄) that is a member of the Olivine Group. It is an excellent birefringent material with a wide transparency range that has extremely low electrical conductivity and superior mechanical properties. It is calcined and milled under controlled conditions and can be modified to meet priority specifications. Synthetic forsterite is available, and it has as high an iron content (<11%) as Fayalite.

Fumed Silica, also known as pyrogenic silica, are powders that are available with either hydrophobic or hydrophilic surfaces. They are made with a flame, resulting in an extremely small particle with a three-dimensional structure with low bulk density and high surface area, making this powder useful as a thickener or reinforcing filler.

Iron (III) hydroxide, Ferric hydroxide (Fe(OH)₃), is frequently used as an adsorbent to remove various heavy metals (i.e., arsenic and chromium) from contaminated soil and water. Ferric hydroxide granular is available in two phases Fe(OH₃) and ß-FeOOH. Please note: Ferric hydroxide slurry is not a stocked product; 2 - 3 weeks lead time is necessary for production. The slurry will discolor over time and separate since Ferric hydroxide is not soluble in water and must be mixed very well before use.

A very fine powder of ferric oxide, Iron(III) oxide, is known as jeweler's rouge, red rouge, or simply rouge. It is used to put the final polish on metallic jewelry and lenses and has been used historically as a cosmetic. Rouge cuts more slowly than some modern polishes, such as cerium(IV) oxide, but it is still used in optics fabrication and by jewelers for its superior finish. It can be applied on buffing wheels by gently pressing the compound to the spinning wheel. The heat and friction of the spinning wheel will transfer a small amount of the compound onto the wheel for polishing. This extremely fine compound will not scratch or cut away the finest or softest of metals and is used to polish gold, silver, brass, copper, and nickel to a mirror finish. When polishing gold, the rouge slightly stains the gold, which contributes to the appearance of the finished piece. Rouge is sold as a powder, paste, laced on polishing cloths, or solid bar (with a wax or grease binder). The rouge cloth has a side impregnated with red jewelers' rouge for polishing and cleaning surface oxidation. The other side is a cloth for final polishing.

Magnesium oxide is a mineral that occurs naturally as periclase and is a source of magnesium.
