Black silicon carbide (SIC) is made from quartz sand and carbon( anthracite coal tar or petroleum coke) in electric esistance furnace at high temperature. It has the characteristic of high hardness, excellent electrical and heat conductivity, low thermal expansion, and high abrasion resistance. Thus, SIC is the most suitable material of abrasives, refractories, deoxidizer of metallurgical, special ceramics, electric heating elements and so on.
Silicon carbide (SiC) is a multifunctional material with high hardness, high thermal conductivity, and certain electrical and thermal conductivity. The following are the main application of silicon carbide:
Other uses: Silicon carbide can also be used to make high-performance ceramics, such as bulletproof ceramic plates;and use make high-temperature structural materials, such as nozzles, combustion chambers, etc.; used to make infrared radiation coatings and far-infrared radiation dryers, etc.
