Silicon Carbide is the only chemical compound of carbon and silicon. It was originally produced by a high temperature electro-chemical reaction of sand and carbon. Silicon carbide is an excellent abrasive and has been produced and made into grinding wheels and other abrasive products for over one hundred years.
Tungsten carbide powder applied to gate Resistant Thermal Spray Coatings of tungsten carbide are used for their hardness and wear resistance. When choosing a Tungsten Carbide Powder, the particle size and type of carbide selected are important in determining the correct material to combat various forms of erosion, abrasion and wear.
Boron carbide, silicon carbide, tungsten carbide, nickel carbide, titanium carbide, and molybdenum carbide were considered. Boron carbide was considered the best candidate because it is commercially available and is relatively inexpensive, even though the surface area is approximately 1 m2/g as compared to 500-1000 m2/g for the activated carbon.
