high quality and low-cost green silicon carbide grain 16#

1 Green silicon carbide is made of quartz sand, petroleum coke (or coal char), salt and other raw materials through high temperature smelting by resistance furnace. It has higher mechanical intensity and hardness than fused alumina. It has a good hardness, strong cutting ability, stable chemical properties and excellent heat-conducting property. 2 Physical index Color Green Moh's hardness 9.4 Specific gravity 3.20g/cm3 Melting point 2600℃ Maximum operation temperature 1900℃ 3 Chemical index SiC 99.05% SiO2 0.2% F.Si 0.03% F.Fe 0.04% C 0.1% 4 Product model 20# 22# 24# 30# 36# 40# 46# 54# 60# 70# 80# 90# 100# 120# 150# 180# 220# 5 product application (1) Bonded abrasive tool (2) Coated abrasive tool (3) Reusable abrasive (4) polishing and lapping
