Product Overview
Description
Brief introduction of black silicon carbide crystals
Black Silicon Carbide crystals is produced in a high temperature electric resistance-type furnace from a mixture of quartz sand and petroleum coke.
The hardness of black silicon carbide is greater than fused alumina but less than synthetic diamond.
Black silicon carbide's mechancial intensity is greater than fused alumina, but brittle and sharp.
Black silicon carbide has some electrical and heat conductivity.
Applications
Bonded abrasive tool
Coated abrasive tool
Reusable abrasive
Grinding,lapping & polishing medium
Resin/Ceramic grinding wheels & grinding media
