Product Description

SUOYI High Hardness purity Sic Silicon Carbide Grains Silicon Carbie Powder

 

Carborundum, also known as silicon carbide (SiC), is made by smelting quartz sand, petroleum coke (or coal coke), wood chips (adding salt when producing green silicon carbide) and other raw materials through resistance furnace at high temperature. 
Silicon carbide also exists in nature as a rare mineral, moissanite. Silicon carbide, also known as carborundum. Among contemporary non oxide high-tech refractory raw materials such as C, N, and B, silicon carbide is the most widely used and economical one, which can be called steel sand or refractory sand. 
At present, the industrial production of silicon carbide in China is divided into two types: black silicon carbide and green silicon carbide, both of which are hexagonal crystals with a specific gravity of 3.20-3.25 and a microhardness of 2840-3320kg/mm2.
