Black Silicon Carbide

Black silicon carbide is mainly made from quartz sand, petroleum coke as the main raw materials and smelted by electric resistance furnace at high temperature. During this high temperature process the crystalline is formed, the grains are extremely hard, sharp, and friable, with many excellent features like as follows.

Brown Corundum

Chrome Corundum

Pink Fused Aluminum Oxide contain chromium oxide, which gives the material its pink color. The incorporation of Cr2O3 into the Al2O3 crystal lattice produces an increase in toughness and a reduced friability compared with White Fused Aluminum Oxide.

Green Silicon Carbide

White Corundum

White Aluminum Oxide(WFA), also known as white Fused Alumina, is a chemical compound of aluminum and oxygen. The most common form of crystalline aluminum oxide is known as corundum. It is electrically fused in an arc furnace at 2050℃with high purity alumina. The final product is used in applications where higher purity levels and lower iron content is desired .
