Silicon carbide
Products Description
With quartz sand and petroleum coke as its main raw materials, black silicon carbide is produced at high temperature in an electric resistant furnace. Its hardness is between corundum and synthetic diamond and its mechanical strength is higher than corundum, which makes it an ideal material for high quality abrasivetools.
Application
1. The most widely application of silicon carbide is producing abrasive tools, such as grinding wheels, cutting disks, etc. Black silicon carbide powder also could used as lapping and polishing media.
2. Black silicon carbide is suitable for processing glass, ceramics, stone, metal, rubber and other materials. 3. Black carborundum also can be used as metallurgical additive and high-grade SiC refractory material
