Product #: SI-501

Product Description

Silicon Nitride is a black gray powder, which is an important structural ceramic material with high hardness, inherent lubricity, and wear resistance. It is an atomic crystal; it is resistant to oxidation at high temperatures. It can resist the impact of cold and heat. It will not be broken if it is heated to above 1000°C in the air, cooled rapidly, and heated rapidly. It is precise because of the excellent characteristics of silicon nitride ceramic that people often use to manufacture mechanical components such as bearings, turbine blades, mechanical seal rings, permanent molds, and so on.
