Polynitrosilane is a new cutting-edge material, which is a ceramic material prepared using polynitrosilane as a precursor. It has properties such as ultra-high temperature resistance, ultra-toughness, ultra-thin, ultra-corrosion resistance, and ultra-high strength.

Polysilazane (PSZ) is a type of inorganic polymer whose main chain consists of Si-N bonds as repeating units. Due to its unique structure, polysilazane can be converted into SiCNO, SiCN, or silica ceramics under high temperature conditions, and the hardness after curing can reach over 8H. Polysilazane has excellent corrosion resistance, oxidation resistance, radiation resistance, and high temperature resistance, and is widely used in fields such as aerospace, semiconductors, photovoltaic cells, high-temperature coatings, ceramic materials, resin materials, etc.

Polysilazanes can be divided into two major categories: organic polysilazanes (OPSZ) and peroxidized polysilazanes (PHPS). Polysilazanes were discovered in the 1880s, but due to complex preparation processes, they only entered the commercial development stage in the 1950s when they were launched. The synthesis methods of polysilazane include ammonia hydrolysis, amine hydrolysis, hydrazine hydrolysis, ring opening polymerization, dehydrogenation coupling method, etc. With the continuous deepening of research, the number of polysilazane synthesis methods will increase.

According to the "2022-2026 Deep Market Research and Investment Strategy Suggestions Report on the Polysilazane Industry" released by the New Scientology Industry Research Center, the active nature of polysilazane and the difficulty of transportation and storage have led to low production capacity in the polysilazane industry, which is concentrated among European and American enterprises. 

Polynitrosilane is a new cutting-edge material, which is a ceramic material prepared using polynitrosilane as a precursor. It has properties such as ultra-high temperature resistance, ultra-toughness, ultra-thin, ultra-corrosion resistance, and ultra-high strength. In recent years, with the development of industrial technology, the global market has continuously released demand for ceramic based materials, which has driven the growth of demand for polysilane. It is expected that the global polysilane market will maintain a compound annual growth rate of over 16.5% from 2022 to 2026.

The preparation technology of polysilazane is difficult, and foreign enterprises monopolize the market. This product follows relevant US trade export laws and is prohibited from being sold domestically. In recent years, in order to break the monopoly pattern of foreign enterprises and fill the gap in the domestic market, Chinese enterprises have conducted research on the technology and application of polysilazane and achieved certain results.
