Varieties and uses of Silicon Carbide

Green silicon carbide black silicon carbide and silicon carbide two commonly used basic varieties, are alpha SiC. 

(1) black silicon carbide containing SiC by about 98.5%, the toughness higher than that of green silicon carbide, mostly used for processing low tensile strength of material, such as glass, ceramics, stone, refractory material, cast iron and nonferrous metal, etc. 

(2) the green silicon carbide containing SiC99 % above, good self-sharpening, mostly used for processing hard alloy, titanium alloy and optical glass, also used for honing cylinder jacket and fine grinding HSS cutting tools. And cubic silicon carbide, it is a special process for making yellow crystals, to make the abrasive tool suitable for bearing the superfinishing, can make the surface roughness from a processing Ra32 ~ 0.16 microns to Ra0.04 ~ 0.02 microns.

Silicon carbide due to the chemical performance is stable, high thermal conductivity, thermal expansion coefficient is small, wear-resisting performance is good, except for abrasive, there are many other USES, such as: silicon carbide powder coated with a special process in the turbine impeller or cylinder wall, can improve the wear resistance and prolong the service life of the 1 ~ 2 times; To made of high-grade refractory materials, thermal shock, small volume, light weight and high strength, good energy saving effect. About 85% low grade silicon carbide (SiC) is an excellentdeoxidizer, use it can speed up steel making, and facilitate the control of chemical composition, improve the quality of steel. In addition, silicon carbide also used to produce large amounts of electric heating element silicon carbon rod.
