The properties of silicon carbide wafer and USES
The hardness of silicon carbide is very big, it has good thermal conductivity and electrical conductivity, can oxidation resistance at high temperature.
(1) as abrasive, abrasive tool can be used to do, such as grinding wheel, whetstone, grinding head, sand tile, etc.
(2) as a metallurgical deoxidizer and high temperature resistant material.
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.
(3) single crystals of high purity, can be used in the manufacture of semiconductor, the manufacture of silicon carbide fibers.
The origin, shipped and quality specifications
(1) origin: qinghai, ningxia, henan, sichuan, guizhou and other places.
(2) : shipped to the United States, Japan, South Korea, and some European countries.
(3) quality specifications:
(1) abrasive grade silicon carbide technology conditions according to GB/T2480-96. The chemical composition of various grades are given in tables the 6-6-47 and 6-6-48.
(2) abrasive particle size and its composition according to GB/T2477-83. Abrasive particle size measurement method according to GB/T2481-83.
