Green Silicon Carbide For Abrasives
1.Size:F12-F1200;
2.Capacity:200MT/month;
3.SiC content:99.0%min;
4.Certificate:ISO9001&REACH
Green silicon carbide is for grinding wheels,heating elements,coated tools,refractory,polishing,electrical,lapping,ceramic Many years experiences.
Green silicon carbide is produced in electric resistance furnace from quartz sand, petroleum coke and salt in high temperature. 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.
