Graphite Powder
Graphite powder is soft and dark gray. In the absence of oxygen, its melting point is above 3000 ℃, and it is one of the most temperature-resistant minerals. The chemical properties of graphite powder are relatively stable at room temperature, and are insoluble in water, dilute acids, dilute alkalis and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, and wear-resistant lubricating materials.
Fused Silica
Fused Silica is made of high purity quartz sand by electrically fused in electric arc furnaces, then the crystalline quartz sand transformed into amorphous silicon dioxide.

Black /Green Silicon Carbide
Silicon carbide is made by high temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), wood chips (salt is needed to produce green silicon carbide) in a resistance furnace. At present, silicon carbide is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals, with a specific gravity of 3.20-3.25 and a microhardness of 2840-3320kg/mm2.

Calcined Bauxite
Calcined bauxite is produced by sintering high-alumina bauxite in rotary, round or shaft kilns at high temperatures. This process of calcining (heating) bauxite in kilns removes moisture and gives calcined bauxite its high alumina content.

White Fused Alumina
White fused alumina (WFA) is obtained from the fusion of high purity calcined alumina in electric arc furnaces. It is the main raw material for the production of medium and high-end shaped and unshaped refractory materials, and is also widely used in the manufacture of ceramics and resin abrasives And sandblasting, grinding and polishing, precision casting, special ceramics and other industries.
