Introduction to the Characteristics and Applications of Silicon Nitride Ball Valves

Silicon nitride ceramics are 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 impact performance, as well as excellent properties such as low coefficient of thermal expansion, low coefficient of friction, anti magnetic, electrical insulation, and small specific gravity. It is considered by the material science community to be a high-tech new material with excellent comprehensive performance and the most promising replacement for nickel based alloys in the high-tech and high-temperature fields in the field of structural ceramics.

The hardness is similar to SiC and mullite, second only to SiC

Good thermal shock resistance, with a thermal shock resistance of 300-800 degrees Celsius

Low high-temperature creep, especially with the addition of a small amount of SiC, exhibits excellent electrical insulation performance

Good wear resistance and self-lubricating properties, similar to the metal surface of oil, extremely excellent wear-resistant material

Good chemical stability, good oxidation resistance, and easy formation of dense SiO2 protective layer on the surface

Main application areas:

1) Mechanical industry: Silicon nitride ceramic shaft balls can be widely used in high-speed machine tools, wind turbine bearings, as well as high temperature and corrosion resistance fields;

2) Metallurgical industry: Due to the non wetting properties of silicon nitride ceramics with aluminum liquid, silicon nitride ceramic components are widely used in aluminum smelting and casting, such as protective tubes, lifting tubes, hooks, etc; Silicon nitride ceramic water blocking rings can be applied to non-destructive testing units for seamless steel pipes; Silicon nitride metallurgical rollers can be used for steel production, etc;

3) The petroleum industry; Can be used for oil exploration, etc;

4) High temperature, wear-resistant, and corrosion-resistant fields; Silicon nitride ceramic positioning blocks can be applied to the production of sponge titanium; The application of silicon nitride ceramic inserts in the high-temperature reflux zone of the swirl burner of supercritical industrial boilers;

5) In the field of transparent materials; Silicon nitride ceramic plates, due to their excellent wave transmission performance, can be applied to the top of microwave ovens and detection windows of material level meters;

6) Automotive components: such as rocker arm inserts, turbine rotors, cam tappets, etc
