Refractories 
1.Description：
Silicon Carbide is produced by heating silica sand and a carbon source, typically petroleum coke, to high temperatures in a large, open “Acheson” furnace. The result of this high temperature process is the crystalline formation of Silicon Carbide grains, of both Green and Black coloring.
2.Characteristics：
Silicon Carbide is high hardness, wear resistance, its chemical inertness, high thermal conductivity, abrasion resistance, low coefficient of thermal expansion, thermal shock resistance, and strength at high temperature ranges.
3.Application：
Silicon Carbide is used in a wide range of applications and industries such as Abrasive, Structure Ceramics, Refractory.
