[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 silicon nitride ceramics have such excellent properties that people often use it to manufacture mechanical components such as bearings, turbine blades, mechanical seal rings, and permanent molds.
