Material properties of silicon nitride ceramic bearings

As an excellent high-temperature engineering material, Si3N4 ceramic material can best exert its advantages in its application in high-temperature fields. The future development direction of Si3N4 is: ⑴ Give full play to and utilize the excellent characteristics of Si3N4 itself ⑵ When sintering Si3N4 powder, develop some new fluxes and study and control the optimal composition of existing fluxes. ⑶Improve powdering, molding and sintering processes

⑴ Give full play to and utilize the excellent characteristics of Si3N4 itself

⑵ When sintering Si3N4 powder, develop some new fluxes and study and control the optimal composition of existing fluxes.

⑶Improve powdering, molding and sintering processes

⑷Develop the composite of Si3N4 and SiC and other materials in order to produce more high-performance composite materials. The application of Si3N4 ceramics in automobile engines has created a new situation for the development of new high-temperature structural materials. The automobile industry itself is a multidisciplinary industry that integrates various technologies. China is an ancient civilization with a long history. It has made brilliant achievements in the history of ceramic development. With the process of reform and opening up, one day, China will also It will inevitably rank among the world's major automobile industry countries and create greater glories for the development of the ceramic industry.

It is extremely resistant to high temperatures, and its strength can be maintained up to a high temperature of 1200°C without decreasing. It will not melt into a melt after being heated and will not decompose until 1900°C. It also has amazing chemical resistance and can withstand almost all inorganic acids. And caustic soda solution below 30%, it can also resist the corrosion of many organic acids; at the same time, it is a high-performance electrical insulation material.
