Silicon Carbide Powder/Lump
Description:
Silicon carbide is an inorganic substance with the chemical formula
SiC. It is made of raw materials such as quartz sand, petroleum
coke (or coal coke), sawdust (salt is needed to produce green
silicon carbide) through high-temperature smelting in a resistance
furnace. In nature, there are also rare silicon carbide minerals
called moissanite. In industry, silicon carbide is divided into
black silicon carbide and green silicon carbide, both of which are
hexagonal crystals with a specific gravity of 3.20-3.25 and a
microhardness of 2840-3320kg/mm2.
Silicon carbide is a compound material composed of silicon (Si) and
carbon (C) with extremely high melting point and hardness. Silicon
carbide has excellent electrical, thermal, mechanical and chemical
properties and is widely used in high-power electronics,
optoelectronics, automotive electronics, aerospace electronics and
other fields.
