China High-purity Silicon nitride white powder CAS 12033-89-5 Si3N4
Product Description:
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, and it will not shatter when heated to above 1000°C in the air, cooled rapidly and heated again sharply.
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.
China, the United States, Japan and other countries have developed this diesel engine.
Advantage:
1.Good thermal conductivity. Second only to diamond in hardness, it is a superhard material,
2.Boron nitride is resistant to chemical attack and is not eroded by inorganic acid and water.
3.Low friction coefficient, high temperature stability, good heat shock resistance, high strength, high thermal conductivity, low expansion coefficient, high resistivity, corrosion resistance, microwave or infrared penetration.
Applications:
1.Used for drill bits, abrasive materials, and cutting tools.
2. High temperature lubricant, release agent.
3. Insulators used in high-voltage high-frequency electricity and plasma arcs, solid-phase admixtures for semiconductors, and structural materials for atomic reactors.
