Black silicon carbide Author:河南新佳晟 Comefrom: Date:2014-4-20 18:34:52 Hits:27

Black silicon carbide is with quartz sand, petroleum coke (anthracite) as the main raw material, formed by high temperature smelting furnace, has a hardness between corundum and diamond, the mechanical strength than corundum, crisp and sharp. The electrical and thermal conductivity of certain. With its production tools, applicable to the processing of low tensile strength of metallic and non-metallic materials. Such as the "gray cast iron, non-ferrous metals, stone, leather, rubber etc.. It is also widely used in refractory, metallurgical additive.
