How much is the price of black silicon carbide?
The main component of black silicon carbide is silicon carbide, and its raw materials are petroleum coke and quartz sand. Its price is mainly determined by the price of black silicon carbide raw material blocks
The current price of black silicon carbide particle size sand is approximately 8500 yuan
The price of black silicon carbide micro powder ranges from 13000 to 20000 (the finer the particle size, the higher the price)
The reason why black silicon carbide micro powder is more expensive than particle size sand is mainly due to the complex production process, the need for acid washing water, and the long production cycle
