[0002] Silicon nitride is an inorganic substance with the chemical formula Si3N4. It is an important structural ceramic material with high hardness, inherent lubricity, wear resistance, and is an atomic crystal; it is resistant to oxidation at high temperatures. It can also resist thermal shocks, and will not break even if it is heated to more than 1000°C in the air, cooled rapidly, and then heated rapidly. It is precisely because of the excellent properties of silicon nitride ceramics that people often use it to manufacture mechanical components such as bearings, turbine blades, mechanical sealing rings, and permanent molds. If silicon nitride ceramics that are resistant to high temperatures and not easy to transfer heat are used to manufacture the heating surface of engine components, it can not only improve the quality of diesel engines and save fuel, but also improve thermal efficiency.
