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.
Silicon carbide (SiC) is a synthetic silicon carbide material that rarely exists in nature. It was discovered in 1890 through synthetic experiments. Then, people used quartz sand and petroleum coke (or anthracite) to synthesize silicon carbide through high-temperature smelting. And industrialized mass production of silicon carbide begins. As additives of thermal resistance and anti-corrosion coatings and paint, green silicon carbide powder plays an important role.
Green silicon carbide is an ideal abrasive blasting media and polishing material for copper and brass.
This week, the silicon carbide price continued to decline. At present, the black silicon carbide price of 98% blocks is reduced by about 50 USD per ton compared with last week in Ningxia & Gansu Province.
Black silicon carbide grain is the main abrasive component of coated abrasives, especially sandpaper. It can be used as wear-resistant material on the surface of the skateboard.
