Ceramic Silicon Nitride Liner Wear Heat Resistant 10×106V M

 

 

 

 

Silicon nitride ceramics is an inorganic material that does not shrink during sintering and is an important structural material. Silicon nitride has high strength and is one of the hardest substances in the world. It has lubricity, and has properties such as wear resistance, high strength, low density, and high temperature resistance. Silicon nitride has a low thermal expansion coefficient and high thermal conductivity, so it has excellent thermal shock resistance. Silicon nitride will not crack when heated to 1000°C and put into cold water. It is extremely resistant to high temperatures, and its strength can be maintained to a high temperature of 1200°C without falling. It will not melt into a melt after being heated, and will not decompose until 1900°C. It also has amazing chemical corrosion resistance. Except for hydrofluoric acid, it does not react with other inorganic acids or caustic soda solutions below 30%, and it is also resistant to corrosion by many organic acids. At the same time, it is a high-performance electrical insulating material. It is precisely because of the excellent characteristics of silicon nitride ceramics that it is more appropriate to replace alloy steel with silicon nitride ceramics in those places where high strength, low density, and high temperature resistance are required. People often use it. To manufacture bearings, turbine blades, mechanical seal rings, permanent molds and other mechanical components.
