An Important Structural Ceramic Material Silicon Nitride Powder

Silicon nitride powder

An inorganic substance with chemical formula Si3N4. It’s a structural ceramic material that is important for durability, lubricity and wear resistance.

Silicon Nitride Properties:

You can find silicon nitride in powder form. It comes in three colors: gray, white and off-white. Silicon nitride powder is highly insoluble at high temperatures, and it has high resistance to high-temperature shrinkage. It has a load softening value of over 1800 degrees Celsius without the use of a binder.

There are two types of silicon nitride crystals: a or b. They both have hexagonal crystals. Its melting temperature in atmosphere is 1800°C and 110°C in nitrogen. The thermal shock resistance of Si3N4 powder is excellent because it has high thermal conductivity as well as a low thermal extension coefficient.

Other than hydrofluoric acid or hot phosphoric acids, silicon nitride doesn’t react with any other inorganic substances and is highly resistant to corrosion.

Silicon Nitride Application:

It is used for making bearings, turbine blades. Seal rings, molds permanent, and other components. The heating surfaces of engine components can be made from silicon nitride clays which can resist high temperatures and transfer heat poorly. This can improve the engine’s quality and fuel efficiency.

As a high-quality refractory, silicon nitride can be used. SI3N4 SIC refractory, for example, is used as a blast furnace body, and in other parts with sic. It is also used when combined with BN (SI3N4BN material) to create a horizontal continuous casting separation ring. SI3N4BN series horizontal continuously casting separation ring with uniform structure is a fine-structure ceramic materials that has high mechanical and structural strength.

Silicon nitride ceramic materials are suitable for use in high temperature engineering components, advanced materials in metallurgical industries, anticorrosion components, sealing components in chemical industry and tools and cutting tools within the machining sector.

You can use silicon nitride in solar cells. Additionally, you can use silicon nitride in gas turbines, plane engines, electric furnaces, and other ultra-high temperature applications.
