GREEN SILICON CARBIDE (GC)
Green silicon carbide is produced basically in the same way of black silicon carbide except the different requirement of raw materials. With higher purity of crystallization and hardness, abrasive tools made of it are suitable for processing hard and brittle materials such as: hard alloy, titanium alloy, bearing stelenon-ferrous metals like copper, brass, aluminum and magnesium, as well as some non-metallic materials including: glassagate ,electrical ceramic, quartz products, rock, gem, ceramics and so on. Green silicon carbide is also used as higher grade refractory materials electrical heating element and elements for electrical appliances.GRAIN TYPES AND GRADES:
