Silicon carbide (SiC) is made from quartz sand, petroleum coke (or coal coke), wood chips (salt is required to produce green silicon carbide) and other raw materials by high temperature smelting through a resistance furnace. Silicon carbide also exists in nature as a rare mineral, moissanite. Silicon carbide is also known as carbonite. In the contemporary C, N, B and other non-oxide high-tech refractory raw materials, silicon carbide is the most widely used, the most economical one, can be called gold steel sand or refractory sand.The silicon carbide content of the companv's products is 97%. 95%. 88%-90%. 80%-85%. 70%-75% and so on: Particle size is main 0-3mm. 0-5mm. 0-8mm. 0-I0mm. 1-3mm.1-5mm.1-8mm.1-10mm.etc.can also be organized according to the special requirements of customers.
