Silicon nitride powder is used in many manufacturing applications where it requires high strength, lubricity and wear resistance. It is also resistant to oxidation at high temperatures and corrosion.
Application: Metallurgy, machinery and aviation industries require ball bearings, sliding bearings, sleeves, valves and other structural components that are able to handle a lot of wear. These materials often require coatings that can withstand intense abrasion and friction, as well as coatings that can protect them from rust and corrosion.
si3n4 powder is an ideal material for these applications, and it can be readily shaped into the various shapes required. It is available in various forms including powders, pellets and targets for thin film deposition.
It can be deposited via plasma enhanced chemical vapor deposition (PECVD) techniques to provide a thin, uniform coating that is resistant to chemicals and thermal shock. It is also a good choice for passivation layers in the fabrication of integrated circuits because it has an excellent dielectric property.
Ceramics:
The primary application of si3n4 powder is in the manufacture of high-temperature ceramics for engineering applications. The material has very good strength, high oxidation resistance and excellent creep resistance at high temperatures and can be processed with a wide range of equipment. The material is also commonly used as a passivation layer in integrated circuits, because it has a very good resistance to water and alkali ions. It is a good dielectric and has excellent optical properties.
