Brown fused aluminum oxide, otherwise known as Brown Fused Alumina or BFA, is produced through an electric arc furnace process. Brown fused aluminum oxide is both a hard (Mohs hardness 9) and tough material with high strength, making it an excellent abrasive grain raw material for applications such as blast media, sandpaper, grinding wheels and abrasive discs, rolls, belts and pads. Its thermal properties make it an excellent raw material for refractory applications, as well.

Green silicon carbide is made of petroleum coke and high quality silica as main raw materials, adding salt as additive, and smelting at high temperature in resistance furnace. Green crystal, brittle and sharp, and has a certain thermal conductivity and electrical conductivity. 

Abrasives Black silicon carbide is made from quartz sand and smokeless acetylene as the main raw material. It is made via light resistance from hydro metallurgical, it is black opaque body hexagonal crystal and MOHS-hardness the 9.15, which is after diamond and boron carbide with crisp and sharp performance and certain degree of conductive heat.
