Green silicon carbide for precision grinding of high-speed steel tools
Description
Green silicon is produced at a high temperature of about 2200 ° C in a resistance furnace. It is green, translucent, and hexagonal, and its Sic content is higher than black one. Physical properties are similar to black silicon carbide, but the performance is slightly more brittle than black, and also has good thermal conductivity and semiconductor characteristics.
