Performance characteristics:Silicon carbide is used Quartz sand, petroleum coke (or coal coke), wood chips (salt needs to be added to the production of green silicon carbide) and other raw materials Resistance furnace It is smelted at high temperature, smelted at high temperature in a resistance furnace, black or green opaque, hexagonal crystal, Mohs hardness is 9.16-9.5。 Second only to diamond and boron carbide, the performance is brittle and sharp and has a certain degree of conductivity
