Sic 97.8% Black Silicon Carbide / Ferro Silicon Carbide for Coated Abrasives

Product Description

SiC 97.8% black silicon carbide / ferro silicon carbide for Coated abrasives
Silicon carbide, also known as carborundum (SiC), is made from high-temperature resistance furnaces using quartz sand, petroleum coke (or coal coke). Silicon carbide also exists in nature as a rare mineral, moissanite . Silicon Carbide is also called Carborite. Among contemporary non-oxide high-tech refractory raw materials such as C, N, B, silicon carbide is the most widely used and economical one, which can be called gold steel sand or refractory sand. At present, silicon carbide produced by Chinese industry is divided into black silicon carbide and green silicon carbide.We can provice different grade,from 50% to 98%
Advantages: 1. Corrosion resistance, high strength, high hardness.
2. Good wear-resisting performance,resist to shock.
3. Silicon carbide is a cost-effective substitute for Ferrosilicon.
4.stable chemical performance, high thermal conductivity, high resistant temperature
