In terms of material coating, polysilazane can be converted into silica under certain conditions. It is a good coating material, with good solubility, excellent adhesion, simple curing, corrosion resistance, oxidation resistance, long-term weather resistance, high and low temperature resistance, transparency and scratch resistance. It is widely used in semiconductor electronic devices, metal protection, plastic packaging and printing industries, as well as Certain anti painting function is widely used in building surface and public transportation.

In terms of ceramic materials, the ceramic precursor prepared by polysilane cracking has the characteristics of easy processing and high temperature and low temperature. It is a new type of organic material. It can be used as an augmented material in the development of aerospace devices, and is widely used in the preparation of high temperature resistant coatings, foam and complex structural components.

In the field of medical operation, through the method of radio frequency glow discharge, polyester coating will be formed in the hexamethyldisilazane steam of surgical elastic suture, which can effectively eliminate the weak tissue damage caused by suture vibration or breakage, and has the characteristics of good hydrophobicity and oxidation resistance. In addition, polysilazane products are widely used to prepare capillary tubes with high thermal stability, high adsorption and no catalytic activity.
