Product Description
Green Silicon Carbide Powder
Green silicon carbide is produced by smelting petroleum coke and high-quality silica in an electric resistance furnace at high temperature. The refined crystal has high purity, high hardness, hardness between corundum and diamond, and mechanical strength is higher than corundum.The SiC purity of green silicon carbide is up to 99%min.With high thermal conductivity and high strength which get no decrease in 1000 centigrade.

Product Application
Applications for green silicon carbide
Green silicon carbide is suitable for processing hard alloys, marble, glass, ceramics, and non-metallic materials. It is also used for semiconductor materials, high-temperature silicon carbon rod heat exchangers, far-red external source substrates, etc. Silicon carbide ceramics made from green silicon carbide have advantages such as high strength, high hardness, wear resistance, good acid and alkali corrosion resistance, and good thermal conductivity, and are widely used in various fields such as bulletproof, chemical engineering, and machinery.
Product Advantage
Silicon carbide produced by Chinese industry is divided into black silicon carbide and green silicon carbide. We can provice different grade,from 50% to 98% The green silicon carbide containing SiC about 97% or above, good self-sharpenness, mostly used for processing hard alloy, titanium alloy and optical glass, also used for honing cylinder liners and grinding high-speed steel cutting tool.
