Silicon carbide powder is not only a common material for abrasives. It also plays an important role in the ceramic industry, especially in combustion appliances.
Non-stick coating on cookware is a special coating with high-temperature resistance and does not stick with food. This coating requires high chemical bond energy and solid physical bonding. Green silicon carbide powder has the characteristics of high hardness, friction resistance, and high-temperature resistance. Non-stick paint manufacturers always add GC powder to the outermost layer of coating. It can increase wear resistance and high-temperature resistance of the coating obviously.
At present, there are many kinds of high-temperature-resistant non-stick coating on the market. Silicone coating and fluorocarbon coating are the most popular. The organosilicon coating has the advantages of low prices and good insulation. However, it will have serious back sticking under high temperatures. Meanwhile, the hardness drops sharply. In order to improve these disadvantages, green silicon carbide powder 1000# can be added to the formula. It will significantly improve the hardness and wear resistance of the coating layer.
Green carborundum grit (GC) is an astonishing grinding medium for ceramics. Compared with black carborundum grit, the green one is sharper. Green carborundum grit for Ceramic grinding can work more efficiently on ceramics.
Magnesite-bonded abrasives are polishing tools for ceramic tiles, ceramics, glass, and other fragile-hard materials. The main raw materials of magnesite abrasive tools are green silicon carbide and magnesite cement. The main points are that there is no edge collapse, good viscosity, high strength, and strong grinding force. Green silicon carbide for magnesite-bonded abrasives is of A-grade carborundum with min 99% purity.
Black silicon carbide is an ideal grinding medium for ceramic parts. It has high hardness and strong grinding force, and can easily grind ceramic components. In the meantime, the grinding efficiency and surface finish can be taken into account by using the appropriate micro-powder model. The D50 particle size of black silicon carbide F400 is 16-18 microns.
At the beginning of the new year in 2023, various abrasive markets are recovering in an orderly manner.
Recently power costs in Northwest China increased. That leads smelting cost of black silicon carbide abrasive up directly.
