Good Performance Green SiC (Silicon Carbide) For Abrasive
Green SiC (Silicon Carbide)
Green Silicon Carbide is produced in electric resistance furnace from quartz sand, petroleum coke
and salt in high temperature. Abrasive Green Silicon Carbide
It’s semi-transparent in green color with crystal structure, high hardness and strong cutting ability,
stable chemical characteristics, good thermal conductivity.
It’s suited for grinding hard, brittle and non-metallic such as cemented carbides, optical glass,
ceramics, etc.
