Silicon nitride ceramic bearings

Silicon nitride ceramic description

Silicon nitride is mainly composed of Si3N4 and has excellent thermal shock resistance and high temperature strength. These properties make it an ideal material for automotive engines and gas turbines. It can be used in various applications such as turbocharger rotors, diesel engine hot swapping, hot swapping, etc.

Silicon nitride has the most versatile combination of mechanical, thermal and electrical properties of any technical ceramic material. It is a high-performance technical ceramic that is very hard and has excellent thermal shock and impact resistance. It exceeds the high temperature performance of most metals and has excellent creep and oxidation resistance. Additionally, its thermal conductivity and wear resistance are among the most demanding in the most demanding industrial applications. Silicon nitride is an excellent choice when high temperatures and high load capabilities are required.
