Zirconia Impeller
Silicon carbide includes black silicon carbide and green silicon carbide. Among them, black silicon carbide is mainly made of quartz sand, petroleum coke, and high-quality silica as raw materials, and is smelted at high temperature in a resistance furnace. Its hardness is between that of corundum and diamond, and its mechanical strength is higher than that of corundum. It is brittle and sharp.
