Product Overview

 

Silicon nitride ceramic is an inorganic material ceramic that does not shrink during sintering. Silicon nitride has high strength, 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.


The product has the advantages of high density and uniformity, excellent thermal shock resistance, corrosion resistance, high temperature resistance, pollution-free, high insulation, and is not affected by a reducing atmosphere. It has a long service life and is especially suitable for harsh conditions such as hydrogen reduction furnaces. Electrode protection. Can be processed according to customer demand specifications.

Silicon nitride ceramic is an advanced structural ceramic material with unique high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance, good oxidation resistance, thermal shock resistance, mechanical shock resistance and small thermal expansion coefficient. Low friction coefficient, anti-magnetic, electrical insulation, small specific gravity and other excellent properties, considered by the material science community as the excellent comprehensive performance in the field of structural ceramics, the most promising alternative to nickel-based alloys in the high-tech, high-temperature field is widely used high technology New material content.

 

Main application areas:
1) Machinery industry: Silicon nitride ceramic shaft balls can be widely used in the electric spindle of high-speed machine tools, bearings of wind turbines, and high temperature and corrosion resistance fields;
2) Metallurgical industry: due to the non-wetting nature of silicon nitride ceramics and aluminum liquid, silicon nitride ceramic parts are widely used in aluminum smelting and casting, such as protection tubes, riser tubes, hooks, etc.; silicon nitride ceramic resistance The water ring can be applied to non-destructive flaw detection units for seamless steel tubes; silicon nitride metallurgical rolls can be used for steel production;
3) Petroleum industry; can be used for petroleum exploration, etc.;
4) The field of high temperature wear resistance and corrosion resistance; silicon nitride ceramic positioning blocks can be used in the production of titanium sponge; silicon nitride ceramic inserts are used in the high temperature reflux area of supercritical industrial boiler swirl burners;
5) In the field of wave-transmitting materials; due to its excellent wave-transmitting properties, silicon nitride ceramic plates can be applied to the roof of microwave ovens, the detection windows of level gauges, etc.;
6) Auto parts: such as rocker inserts, turbine rotors, cam tappets, etc.
