CHEMICAL,PROPERTIES AND SIZES OF SILICON CARBIDE
Silicon carbide is produced in electrical internal resistance furnaces from silica sands and petroleum coke(added salt during smelting when produce green silicon carbide).
Zhengzhou haixu abrasives co.,ltd,as the main producer of silicon carbide from China,founded in 1999,has been producing and exporting silicon carbide for more than 20years.
What about the quality of silicon carbide from haixu abrasives?
