Silicon nitride is an inorganic substance with the chemical formula Si3N4. It is an important structural ceramic material with high hardness, lubricity, wear resistance, atomic crystal, and oxidation resistance at high temperature. Moreover, it can also resist cold and heat shocks. It will not shatter when heated to over 1000°C in the air, and it will be cooled rapidly and then heated rapidly. Except for hydrofluoric acid and hot phosphoric acid, it does not react with other inorganic acids and has strong corrosion resistance.

It is precisely because silicon nitride ceramics have such excellent characteristics that people often use it to manufacture mechanical components such as bearings, gas turbine blades, mechanical seal rings, and permanent molds. If silicon nitride ceramics with high temperature resistance and low heat transfer are used to make the heating surface of engine parts, it can not only improve the quality of diesel engines, save fuel, but also improve thermal efficiency. Silicon nitride ceramic is an advanced structural ceramic material. It is considered by the material science community as a high-tech technology with excellent comprehensive performance in the field of structural ceramics and the most promising alternative to nickel-based alloys in high-tech and high-temperature fields.
