Silicon nitride ceramic material is a special ceramic material with excellent comprehensive performance; Shandong Industrial Ceramics Research and Design Institute Co., Ltd. has more than 40 years of research and development experience in silicon nitride ceramic materials, and has undertaken more than 30 countries. From the "Sixth Five-Year Plan" to the "Twelfth Five-Year Plan", the national key research projects, high-tech projects and military research projects have won 17 research results at the ministerial level and above, and obtained 6 patents. They were established as early as the mid-1990s. "800,000 Si3N4 ceramic bearing ball" and special-shaped product production line form a research and development platform for Si3N4 ceramic products integrating scientific research and production; it has a complete set of production process equipment from raw material processing, forming, firing and processing.
Main application areas:
1) Machinery industry: Silicon nitride ceramic shaft ball can be widely used in electric spindles of high-speed machine tools, wind turbine bearings and high temperature and corrosion resistant fields;
2) Metallurgical industry: Due to the non-wetting characteristics of silicon nitride ceramics and aluminum liquid, silicon nitride ceramic parts are widely used in the smelting and casting of aluminum, such as protective tubes, riser tubes, hooks, etc.; The water ring can be applied to the non-destructive testing unit of seamless steel pipe; the silicon nitride metallurgical roll can be used for steel production;
3) petroleum industry; can be used for oil exploration, etc.;
4) high temperature wear resistance and corrosion resistance; silicon nitride ceramic positioning block can be applied to the production of sponge titanium; silicon nitride ceramic insert is applied to the high temperature recirculation zone of supercritical industrial boiler swirl burner;
5) In the field of wave-transparent materials; silicon nitride ceramic plates can be applied to the top of microwave ovens, the detection window of the level gauge, etc. due to their excellent wave-transmission performance;
6) Auto parts: such as rocker arm inserts, turbine rotors, cam tappets, etc.
