WHAT IS SILICON CARBIDE?
First silicon carbide usually include black silicon carbide and green silicon carbide.
black silicon carbide
Silicon Carbide is a kind of inorganic substance,its chemical formula is SiC.
The raw material of silicon carbide is silica sand and petroleum coke,and melted in resistance furnace,then cool.
There is one thing that will add some salt when produce green silicon carbide,but needn’t it when black silicon carbide.
Silicon Carbide is hexagonal crystal, its specific gravity is 3.2-3.25g/cm3 and microhardness is 2840～3320kg/mm2.
Zhengzhou haixu abrasives co.,ltd,founded in 1999,has produced silicon carbide more than 20years.
We produce black silicon carbide and green silicon carbide,mainly used for sandblasting,grinding,lapping,ceramic,coating and abrasive tool etc.
And the sizes of black silicon carbide is as follows:
