Silicon nitride, a material with strong potential, has gradually attracted wide attention in recent years. With its outstanding properties such as high hardness, good thermal stability and chemical inertness, silicon nitride has become an important player in many fields.
1. What is silicon nitride
Silicon nitride, chemical formula Si3N4, is a new inorganic nonmetallic material composed of silicon and nitrogen. Made by reacting silicon and nitrogen at high temperatures, its crystal structure consists of two tetrahedrons of different sizes, one of which consists of silicon atoms and the other of nitrogen atoms. This structure gives silicon nitride unique physical and chemical properties.
2. Use of silicon nitride
Aerospace and Automotive Manufacturing:
Silicon nitride has high hardness, high temperature resistance and corrosion resistance, so it has become an important material in aviation and automotive manufacturing. For example, it can be used to make components for turbine engines, as well as bearings and seals in cars.
In semiconductor manufacturing, silicon nitride is used as a thin-film deposition material to enhance the insulating properties and mechanical strength of chips. It can also act as a protective film to prevent the chip from being contaminated during the manufacturing process.
Silicon nitride ceramics have excellent wear resistance and high temperature stability, so they are widely used in the manufacture of advanced ceramic products, such as the blades of gas turbines, as well as high-precision bearings.
Silicon nitride is also widely used in the medical field due to its biocompatibility and hypoallergenicity. For example, it can be used to make medical implants such as artificial joints and dental plants.
Silicon nitride coatings can be used to create efficient and corrosion-resistant membrane filters for a variety of water treatment applications.
