Green Silicon Carbide GC
Ø Feature
Green Silicon Carbide GC is the finest powder that are crushed and sized by advanced fine powder technology using green silicon carbide abrasive as raw material. In addition to maintain hardness close to diamond, it is also excellent in grinding and polishing properties which will not be affected by chemicals.
Ø Physical Properties and Chemical Composition
l Raw Material:carbon material and silica stone as the main raw materials melted in an electric furnace.
l Chemical Name:α-SiC (silicon carbide)
l Structure:green hexagonal crystalline
l Melting Point:2220°C
l Hardness:Mohs 13
Ø Application
l Materials for precision finishing grinding wheels (magnetic heads, etc.) and high-grade polishing grinding wheels
l Cutting and precision lapping materials for quartz, silicon and various glass and magnetic materials
l Cutting and precision lapping materials for ceramics, cemented carbide, new material, etc
