At the bottom of March, several manufacturers of green carborundum blocks issued price increase notifications. That is the fourth time to increase the price in a month. The green carborundum price raised about 320 USD per ton after the Chinese new year.
SiC Carborundum powder(Silicon carbide powder) is an industrial material with high-temperature resistance and excellent thermal properties. Carborundum powder has strong chemical stability at high temperatures. In the meantime, it is stable strength at high temperatures and low thermal expansion rate. Carborundum powder is an indispensable material for composite ceramics and industrial ceramics. In the projects from our customers, black carborundum powder, and green carborundum powder are used by end-users.
High quality green silicon carbide powder has to get high silicon carbide content, few impurities, narrow particle size range.
Green silicon carbide micron is a kind of non-metallic abrasive with high hardness, high mechanical strength. It can make an aggressive grinding. Green silicon carbide has great advantages for the grinding of PZT (piezoelectric ceramic) materials.
From the end of February 2022, the price of the raw materials for silicon carbide anthracite and petroleum coke has raised. The price increasing rate is about 65-80 USD per ton. So the price of silicon carbide grit and silicon carbide powder has also been raised. In China, silicon carbide manufacturers are considering raising prices in the near future.
Among the known high strength and high refractoriness materials, many materials are expensive new materials. As a man-made material, silicon carbide material has excellent high-temperature oxidation resistance, chemical corrosion resistance, strength, toughness and heat resistance.
