Vinyl silazane is an organic silicon compound containing silicon, nitrogen and vinyl groups. Its molecular structure features alternating connections of silicon and nitrogen atoms, forming stable ring or chain frameworks. The vinyl groups act as active functional groups, endowing it with good reactivity. 
This compound typically exists in a colorless to pale yellow liquid state, with low viscosity and good volatility. It is relatively stable in chemical properties at room temperature, but under high temperature or the action of a catalyst, the vinyl groups can undergo polymerization reactions, forming cross-linked polymer structures. Its unique structure enables it to possess the flexibility of organic materials and the high-temperature resistance of inorganic materials, with a wide temperature range of resistance to both high and low temperatures, maintaining stable performance at -60°C to 300°C. 
The preparation of vinyl silazane is mostly achieved through the condensation reaction of organic silicon monomers and nitrogen-containing compounds. Common raw materials include vinyl chlorosilane and amine compounds. During the reaction process, strict control of temperature and reaction time is necessary to increase the yield. 
In application fields, vinyl silazane is an important precursor for preparing high-temperature resistant ceramic materials. After high-temperature cracking, it can be transformed into silicon-nitrogen ceramics, used for high-temperature components in aerospace fields; at the same time, it can also be used as a surface treatment agent, improving the adhesion and corrosion resistance of the material, with broad application prospects in the electronics and chemical industries.
