Organic silicon is an organic compound that is connected to silicon atoms through organic groups such as oxygen, fluorine, sulfur, and nitrogen. However, in the world of starry organic silicon compounds, compared to research on silicon oxide, silicon fluorine, sulfur, etc., there is clearly too little attention paid to the unique "silicon nitride" galaxies in the vast universe. Silazane polymer (also known as polysilazane) is a compound with Si-N bond structure as the main chain. Due to the relatively active nature of most silazanes, their preservation and transportation are difficult, and the preparation methods of silazane polymers are not effective in controlling the reaction products. This difficult to tame characteristic has led to the discovery of polysilazane polymers. Since the first report in 1921 on the use of ammonia ammonia to hydrolyze chlorosilane to prepare polysilazane, researchers have been studying polysilazane for nearly a century until the 1990s, when R The Reidel research team prepared Si-B-C-N ceramics by introducing B element into polysilazane, and researchers have shifted their focus to various modified polysilazane.

Breaking through obstacles in the application research and preparation process of polysilazane, chlorosilane, silazane, organic polysilazane resin, polysilazane cured products (cross-linked Si-C-N-H organic-inorganic hybrid materials), amorphous ceramics (Si-C-N materials), crystalline ceramics (SiN, SiC materials), etc., continuously exploring new materials of polysilazane in the field of organic silicon.  

With the widespread application of high-performance, efficient, safe, and environmentally friendly coatings in the national economy and defense industry, they have become a functional material with great scientific research and potential for more applications. In the future, with the advancement of technology, it will play a greater application value. Polysilazane (PSZ) is a type of inorganic polymer with Si-N bonds as the repeating unit in the main chain. Polysilazane can be divided into two categories: organic polysilazane (OPSZ) and superhydrogenated polysilazane (PHPS). Due to its unique structure, polysilazane can be converted into SiCNO, SiCN, or silica ceramics under high temperature conditions, and its hardness can reach over 8H after curing.   

Polysilazane has excellent corrosion resistance, oxidation resistance, radiation resistance, and high temperature resistance, and is widely used in aerospace, semiconductors, photovoltaic cells, high-temperature coatings, ceramic materials, resin materials, and other fields. Silazane polymers can be converted into SiCN, SiCNO, or silica ceramics under high temperature conditions, making them of great application value in high-temperature resistant coatings.

Polysilazane can be divided into two categories: organic polysilazane (OPSZ) and perhydrated polysilazane (PHPS). Polysilazane was discovered in the 1880s, and due to its complex preparation process, it only entered the commercial development stage in the 1950s when it was launched. The synthesis methods of polysilazane include ammonolysis, amination, hydrazine hydrolysis, ring opening polymerization, dehydrogenation coupling, etc. With the continuous deepening of research, the number of polysilazane synthesis methods will increase.
