Silicon Carbide is a non oxide ceramic and is used in a wide range of products that must perform in thermally (high heat and heat shock) and mechanically demanding appliions. It is employed in both abrasives and wear resistant parts for its hardness; in refractories and ceramics for its resistance to heat and low thermal expansion; and in electronics for its thermal conductivity and other
