Description

Silicon Nitride
Si3N4

 

Silicon nitride is mainly composed of Si3N4, which has excellent heat shock resistance and high temperature strength. These characteristics make it an ideal material for automobile engine and gas turbine. It can be used in turbocharger rotor, hot plug and hot plug in diesel engine, as well as in many other applications.

 

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 extremely hard and has exceptional thermal shock and impact resistance. It surpasses most metals high temperature capabilities and has a superior combination of creep and oxidation resistance. Additionally, its low thermal conductivity and high wear resistance make it an excellent material that can withstand the toughest of conditions in the most demanding industrial applications. Silicon Nitride is an excellent choice when high-temperature and high-load abilities are needed.

Structure

Great Ceramic has rich experience in milling, grinding and polishing precision (Advanced) ceramics and firing ceramics, which enables us to achieve:

  • The shape of the product can be customized according to technical drawings or samples;
  • When the dimensional accuracy of product shape is the best, it can reach ±0.003mm, which is generally controlled within ±0.05mm;
  • When the internal structure accuracy of the product is the best, it can reach ±0.01mm, which is generally controlled within ±0.05mm;
  • The surface roughness of silicon nitride ceramic can reach within Ra0.02um after polishing, and within Ra0.4-Ra0.6 under general polishing state;
  • We can add arcs, grooves, threads and other structures internally;
  • Contact us for more information on structure or accuracy;
