SiC ceramic seal ring material-black silicon carbide F120#
Description:
Black silicon carbide is produced by smelting quartz sand, petroleum coke (or coal coke), wood chips, and other raw materials in a resistance furnace. It appears as a black opaque body with hexagonal crystals and a Mohs hardness of 9.15. Second only to diamond and boron carbide, it possesses brittle and sharp properties with a certain degree of conductivity.It appears as a black opaque body with hexagonal crystals and a Mohs hardness of 9.15.
