1. Black silicon carbide description:
Black silicon carbide is quartz sand, petroleum coke in primary raw materials, smelting in the high temperature resistance furnace. Its hardness is between corundum and diamond; the mechanical strength is higher than alumina, brittle and sharp. It has a certain conductivity and thermal conductivity.
(1) As the abrasive: used for abrasive, such as grinding wheels, whetstone, grinding wheel, sand tiles etc.
(2) As the metallurgical deoxidizer and high temperature material.
Four main application areas of SiC: functional ceramics, advanced refractory, abrasives and metallurgical materials.
(3) High purity single crystal, used to manufacture semiconductors, manufacture of silicon carbide fibers.
(4) Silicon carbide is very hard, with excellent thermal conductivity, as a semiconductor and high temperature resistant to oxidation.
