The main characteristics of silicon nitride

Overview of silicon nitride Si3N4 powder

Silicon nitride Si3N4 powder is an inorganic substance with the chemical formula Si3N4. Si3N4 is an important structural ceramic material with high hardness, inherent lubricity, wear resistance, atomic crystallinity and high temperature oxidation resistance.

The main characteristics of silicon nitride

In addition to excellent mechanical properties, silicon nitride exhibits a range of excellent thermal properties, making it suitable for demanding industrial applications. Thermal conductivity is the inherent ability of a material to transfer or conduct heat. Heat transfer coefficient is a key factor in characterizing engineered materials for any industrial application under extreme temperature requirements. Due to its unique chemical composition and microstructure, silicon nitride has the same low thermal conductivity as metals.

Silicon nitride has excellent stability due to its strong atomic bonds, which makes the material highly resistant to corrosion by acid-base solutions at room temperature. This is critical when considering long-term human implantation in saltwater environments. The corrosion resistance is mainly attributed to the formation of oxide layers on the surface of the material. The same resistance was observed when silicon nitride was exposed to hot gases, molten salts and metals and subjected to corrosion tests in a complex environment. The formation of oxide layers plays a central and complex role in the corrosion resistance of materials.

Due to its self-reinforcing microstructure, extremely high strength and toughness, and many excellent properties, silicon nitride has become an attractive structural component for many applications in various industries, including biomedical applications.
