Polysilazane is an organic polymer containing silicon (Si) and nitrogen (N) bonds, known for its exceptional high-temperature stability, chemical resistance, and ceramic conversion capability. These properties make it widely used in coatings, refractory materials, and electronic encapsulation. One of its most remarkable features is its ability to decompose under high temperatures, transforming into silicon nitride or silicon carbide ceramics, which endow the final product with excellent heat resistance and mechanical strength.

Polysilazane is commonly utilized in the production of ultra-high-temperature ceramic materials, making it suitable for aerospace applications, engine protective layers, and heat-resistant coatings. With its low thermal expansion coefficient and high hardness, it is also an outstanding choice for protective coatings on electronic components, enhancing their wear resistance and oxidation resistance. Additionally, this material serves as a reinforcing agent for high-performance composites, improving the thermal and mechanical properties of carbon fiber or ceramic matrix composites.

In coating applications, polysilazane’s excellent film-forming properties make it ideal for automotive paint surfaces, glass protective coatings, and other advanced protective layers, providing self-cleaning, anti-corrosion, and wear-resistant properties. As material science continues to advance, polysilazane is expected to play a crucial role in high-temperature materials, aerospace, and high-end electronics industries.
