SiC powder
At present, the industrial production of silicon carbide is divided into black silicon carbide and green sic two, are six square crystals, the proportion of 3.20~3.25, microhardness of 2840~3320kg/mm2 .
SIC has black silicon carbide and green silicon carbide two commonly used in this species, are α-sic.
① black sic containing sic about 95%, its toughness is higher than green silicon carbide, mostly used for processing of low tensile strength materials, such as glass, ceramics, stone, refractories, cast iron and Nonferrous metals.
② green sic containing sic about 97% , self-sharpening good, mostly used in the processing of cemented carbide, titanium alloy and optical glass, also with honed grinding cylinder liner and precision grinding high-speed steel tools. In addition to cubic silicon carbide, It is a special process for the production of Yellow-green crystals, used to make abrasives suitable for the super-finishing of the bearing, can make the surface roughness from Ra32~0.16 microns once processing to Ra0.04~ 0.02 Microns.
use: Silicon Carbide has four main application fields, namely: functional ceramics, High refractories, abrasives and metallurgical Raw materials.
