Black silicon carbide ,Green Silicon Carbide , SIC Powder with factory price
Black Silicon carbide (SiC) is made from quartz sand and petroleum coke( or coal tar), wood chips as raw material through high temperature smelting in electric resistance furnace.
Advantages
1.Corrosion resistance, high strength, high hardness,
2.Good wear-resisting performance,resist to shock
3.Stable chemical performance, high thermal conductivity, high resistant temperature

Advantages:
(1) Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.
(2) Good hardness, longer life.
(3) Chemical washed and water washed good cleanness.
(4) Special treated products get higher purity, better toughness, and better grinding effect.
1 Due to its extreme hardness it has good wear and abrasive resistance then it can be used as not only lapping and polishing material such as the polishing of high speed steel but also cutting tools for hard metal wire drawing dies abrasive tools with high abrasive and wear resistance sealed washer (gasket) and the nozzles for water jet cutters slurry pumping grit blashing etc
2 To take place of diamond in the processing of semiprecious gems such as ruby synthetic corundum etc
3 As the raw material for refractory industry special welding etc
4 To be used as raw material for ballistic armour and relative products
5 Due to its capability to generate tremendous amount of heat in combination with oxygen boron carbide is used as rocket propellant in aerospace industry
