Main Classification and Applications of Silicon Carbide

Depending on the purity of silicon carbide, it is mainly divided into green silicon carbide and black silicon carbide, and their applications are also different.

A, Black silicon carbide contains SiC about 98.5%, whose toughness is higher than green silicon carbide, mostly used for processing low tensile strength materials, such as glasses, ceramics, stone materials, refractory materials, cast iron, nonferrous metal, etc. Green silicon carbide contains SiC above 99 %, which has good self-sharpening, mostly used for processing hard alloy, titanium alloy and optical glass, and also used for honing cylinder jacket and fine grinding HSS cutting tools.

B, In addition, silicon carbide also has a special variety, which is called cubic silicon carbide that is a special yellow-green crystal, used in finish machining industry. Its micro processing effect is great.

Silicon carbide has stable chemical performance, high thermal conductivity, small thermal expansion coefficient, good wear-resisting performance, so it not only can be used as abrasives, but also has many other applications. For example, you can daub silicon carbide powder in the turbine impeller or cylinder wall with a special process, which can improve the wear resistance and prolong the service life about 1 ~ 2 times; High-grade refractory materials made of silicon carbide, have good thermal shock resistance, small volume, light weight, high strength, and good energy saving effect.

The hardness of silicon carbide is very big, and it has good thermal conductivity, and is a kind of semiconductor that can have oxidation resistance at high temperature.
