Silicon carbide (SiC) is using quartz sand and petroleum coke or coal tar, wood
chips (green silicon carbide production need to add salt) such as raw material
through high temperature electric resistance furnace smelting. There is also a
rare mineral silicon carbide in nature, and the mo SangShi. Silicon carbide is
also called the moissanite. In contemporary C, N, B the oxide refractory raw
materials in the high technology, such as silicon carbide as the most widely
used, one of the most economic, can be called corundum or refractory sand. At
present China's industrial production of silicon carbide is divided into two
black silicon carbide and green silicon carbide, are the six-party crystal,
specific gravity is 3.20 ~ 3.20, the microhardness of 2840 ~ 3320 kg/was.
Silicon carbide mainly has four major application fields, i.e., functional
ceramics, refractories, abrasives, metallurgical raw materials. Silicon carbide
raw material supply can have a lot of, can't calculate high-tech products, and
the application of high technology content of nano-sized sic powder short time
can't form scale economy.
(1) as abrasive, abrasive tool can be used to do, such
as grinding wheel, whetstone, grinding head, sand tile, grinding brush, etc.
(2) as metallurgical deoxidizer and high temperature resistant material.
(3) single
crystals of high purity, it can be used in the manufacture of semiconductor, the
manufacture of silicon carbide fibers.
