At present, China " s industrial production of silicon carbide is divided into two types of black silicon carbide and green silicon carbide, are hexagonal crystals, the specific gravity of 3.20 ~ 3.25, microhardness of 2840 ~ 3320kg/mm2.
At-soo-saarka la joogo Shiinaha ee warshadaha ee carbide Silicon waxaa loo qaybiyaa laba nooc oo carbide Silicon madow iyo carbide Silicon cagaaran, waa kiristaalo hexagonal, xisaabiyenimo 3,20 in 3.25, microhardness 2840 ~ 3320kg / mm2
