Preparation of Polysilazane Materials: High purity silazane precursors with expected polymerization degree were prepared by ring opening polymerization using octamethylcyclotetrasilazane as raw material. The products have achieved breakthrough results in the fields of military ceramic fibers, aerospace bearing wear-resistant coatings, high-temperature coatings, etc.
In the field of semiconductor and microelectronics, octamethylcyclotetrasilazane is used as a precursor for chemical vapor deposition (CVD) or atomic layer deposition (ALD) in semiconductor device manufacturing. Silicon nitride and other insulating films are deposited on the surface of semiconductor wafers for use in gate insulation layers, interlayer insulation layers, etc. of chips to improve their performance and reliability. For example, chip manufacturing companies such as Intel and Samsung use related technologies in advanced process chip production.
Photovoltaic industry: Octamethylcyclotetrasilazane can be used to prepare weather resistant and self-cleaning coatings for photovoltaic modules. Outdoor photovoltaic panels are exposed to sunlight, rainwater, and other environments for a long time. Coating with octamethylcyclotetrasilazane can improve the weather resistance of photovoltaic panels, reduce the adhesion of pollutants such as dust, and improve the photovoltaic conversion efficiency and service life of photovoltaic panels. Photovoltaic companies such as Longi Green Energy may apply it in related products.
Rubber product modification: Octamethylcyclotetrasilazane can be used to modify silica in high-performance rubber products. When preparing a high-performance rubber product, octamethylcyclotetrasilazane is reacted with an intermediate to produce modified silica, which is then combined with porous silica to form a composite as a reinforcing agent for the rubber. This ensures that the rubber product maintains good tensile strength, elongation at break, tear strength, and resilience even after prolonged storage, and has excellent heat resistance.
In the field of surface treatment, metal materials work in high-temperature and highly corrosive environments such as aviation engines. Octamethylcyclotetrasilazane is used to treat the metal surface, forming a protective film containing silicon nitrogen bonds, which can improve the metal's high temperature resistance and corrosion resistance. In the surface treatment of aircraft engine blades, the application of relevant technologies can extend the service life of the blades, improve the reliability and efficiency of the engine.
