Silicon Nitride (Si3N4) ceramic material is an inorganic material ceramic that does not shrink during sintering. Silicon Nitride (Si3N4) is very strong, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. With high strength, low density, high temperature resistance and other properties, it is a high-performance electrical insulating material.
Silicon Nitride (Si3N4) ceramics has a low coefficient of thermal expansion, high thermal conductivity and excellent thermal shock resistance. As an excellent high-temperature engineering material, Si3N4 ceramic material can best exert its advantages in its application in high-temperature fields.
Silicon Nitride (Si3N4) shows us the greatest cross-sections of material properties across the technical ceramic groups, this makes it a structural ceramic with the best comprehensive properties, and able to provide specialist solutions for those harshest industrial working conditions on earth.
In recent years, silicon nitride ceramics have made great strides in a number of industrial applications, which allowed great flexibility and customization to create precisely the parts needed.
In general, the applications of silicon nitride ceramic parts include but are not limited to:
Parts subject to high stress, such as ball bearing, roller bearing, and automotive components
Parts subject to rapid temperature changes
Parts requiring high strength, even at high temperature
Parts requiring high-temperature resistance and high-load abilities
Parts requiring high resistant to abrasion and low friction
