silicon nitride ceramics Silicon nitride ceramic is an inorganic material ceramic that does not shrink during sintering. The strength of silicon nitride is very high, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density, high temperature resistance and other properties. High temperature resistance, the strength can be maintained to a high temperature of 1200 without decreasing, and will not melt into a molten body after being heated, and will not decompose until 1900 It has amazing chemical corrosion resistance, and can withstand almost all inorganic acids and less than 30% caustic soda solution, as well as many organic acids; It is also a high-performance electrical insulating material. Si3N4 can be used to manufacture ball bearings by virtue of its light weight and high rigidity. It has higher accuracy than metal bearings, generates less heat, and can operate in higher temperatures and corrosive media. The steam nozzle made of S ceramic has wear resistance, heat resistance and other characteristics, and it will not be obviously damaged after being used in 650 boiler for several months.
