Poly (silyl) nitrides (PSN) are a type of inorganic polymer material with unique properties, typically featuring alternating connection structures of silicon, nitrogen, and carbon elements. They are commonly used in high-temperature, corrosion-resistant, and high-strength engineering applications. It is a polymer formed by covalent bonding between silicon and nitrogen atoms, structurally similar to a siloxane (Si-O) chain, but with oxygen atoms replaced by nitrogen atoms. This unique structure endows polysilazane with the following significant physical and chemical properties:
1. High temperature stability: Polysilazane has excellent thermal stability and can maintain stability at temperatures above 1000 ° C. It exhibits excellent heat resistance in an inert atmosphere and maintains a certain degree of stability in oxidizing environments, making it an important material for high-temperature environments such as aerospace and military.
2. Excellent mechanical properties: Polysilazane maintains high mechanical strength at high temperatures, especially in high-temperature environments, with good compressive strength, hardness, and toughness. Its lower coefficient of thermal expansion makes it less prone to cracking during thermal cycling, making it suitable for high stress working conditions.
3. Corrosion resistance: Polysilazane exhibits excellent corrosion resistance and can resist corrosion from various chemical media, such as acid, alkali, etc. This makes it widely applicable in the chemical industry and harsh environments.
