Silicon carbide usually is devided to black silicon carbide and green silicon carbide or α-SiC and β-SiC,which all made from silica sands and petroleum coke.
Zhengzhou haixu abrasives co.,ltd,founded in 1999,has been producing and exporting silicon carbide from more than 20years,we produce mirco grade α -sic black silicon carbide and green silicon carbide,nano α-sic and β-SiC silicon carbide.
Today we just mainly introduce our Nano grade β-SiC Silicon cabride,the mail specification is as follows:
