silicon carbide used for refractory and abrasive ,we are the manufacturer to export it with high quality and good price
Production Description:
Green silicon carbide is produced basically in the same way as black silicon carbide except the different requirement of raw material. With higher purity of crystallization and hardness, when abrasive tools use of it, they are suitable of processing hard and brittle materials such as: Hard alloy, titanium alloy, bearing steel as well as some non-metallic material including: Glass, agate, electrical ceramic, quartz products, rock. Green silicon carbide also used as higher-grade refractory materials, electrical heating element and elements for electrical appliances.
