Silicon Nitride Ceramic:

The similarities and differences between traditional ceramics and special ceramics are as follows: 1) In the raw materials, the boundaries of traditional ceramics with clay as the main raw material have been broken. Special ceramics generally use oxides, nitrides, borides and carbides as the main raw materials. 2) In terms of composition, the composition of traditional ceramics is determined by the composition of clay, so ceramics of different origins and kiln have different textures. Since the raw materials of special ceramics are pure compounds, the composition is artificially determined and its properties are excellent. Inferior raw material purity and process, not determined by the place of origin 3) In the preparation process, it breaks through the boundaries of traditional ceramic kiln as the main production means, widely used vacuum sintering, protective atmosphere sintering, hot pressing, hot isostatic pressing 4) In terms of performance, special ceramics have different special properties and functions, such as high strength, high hardness, corrosion resistance, electrical conductivity, insulation, and special functions in magnetic, electrical, optical, acoustic, and biological engineering. So that it is widely used in high temperature, mechanical, electronic, aerospace, medical engineering. Particle dispersion and toughening is to add a certain particle size of particles with high elastic modulus in Si 3N 4 ceramics, such as SiC, TiC, TiN, etc., which causes the crack to deflect and bifurate when the material breaks, and consumes the fracture energy. Methods for improving the toughness of silicon nitride ceramics In recent years, many studies have been conducted on the introduction of second phase particle dispersion and toughening Si 3N 4 composite materials. The method is simple in process, inexpensive, easy to mass produce and accepted by the market.
