Silicon nitride ceramic wheel

SHENZHEN HAORUI INDUSTRIAL Silicon nitride ceramics have the most versatile combination of mechanical, thermal and electrical properties and are a high-performance technical ceramic. It has a high temperature capability that exceeds most metals, and has excellent creep and oxidation resistance. In addition, its excellent thermal shock resistance and high abrasion resistance make it an excellent material capable of withstanding the harshest conditions in the most demanding industrial applications.

Silicon nitride ceramics are very wear-resistant because of their superior hardness and self-wetting properties. In addition, silicon nitride ceramics do not react with other inorganic acids except hydrofluoric acid, making it highly resistant to corrosion. Moreover, it has excellent resistance to thermal shock and will not rupture when heated to 1000°C in air and then rapidly cooled.

Application industry:

Machinery, electronic, semiconductor, chemical, petroleum, smelt.

Specific application:

Welding shaft, electronic substrate, plunger, nozzle, slide guide, diesel parts, metal molding, shaft wheels etc.
