Black silicon carbide is a high purity black silicon carbide refractory grain, which is made by fusing quartz and coke in high power electrical furnace. It characterizes the high hardness, wear resistance ability, corrosion resistance ability and high-temperature strength.
It is also an excellent antioxidant in steel melting industry, can be used in making smelting furnace lining, high-temperature furnace components, sic plate, support cases and sic crucible. Cabrmc is also a very good non-ferrous metal smelting industry indirectly heated high-temperature materials.
