Product Description

SUOYI White Silicon Nitride Si3N4 powder CAS 12033-89-5 for Ceramic

Silicon nitride is an inorganic substance with the chemical formula Si3N4. It is an important structural ceramic material, characterized by high hardness, inherent lubricity, and excellent wear resistance. It is an atomic crystal that exhibits oxidation resistance at high temperatures. Moreover, it can withstand thermal shock. Even when heated to above 1000°C in the air, and then rapidly cooled and heated again, it will not crack.

 

Precisely because silicon nitride ceramics possess such excellent properties, people often use them to manufacture mechanical components such as bearings, turbine blades, mechanical sealing rings, and permanent molds. If silicon nitride ceramics, which can withstand high temperatures and are not prone to heat transfer, are used to manufacture the heated surfaces of engine components, it can not only improve the quality of diesel engines and save fuel but also enhance the thermal efficiency. China, as well as countries like the United States and Japan, have all developed such diesel engines.
