A polysilazane (silazane-based polymer) is a material having a polymeric chain structure based on alternating silicon and nitrogen atoms. Polysilazanes have have both linear, cyclic, and fused cyclic
chain segments.
Polysilazanes are colorless to pale yellow liquids or solid materials. Conditional of manufacturing, the liquids often contain dissolved ammonia that can be detected by smell.
The essential feature of a polysilazane is a structural framework of backbone made up entirely of alternate silicon and nitrogen atoms, with no carbon atoms or chains of carbon atoms in the "backbone" itself.
Ammonia and chlorosilanes, both readily available and low-priced, are used as starting materials in the synthesis of polysilazanes. In the ammonolysis reaction, large quantities of ammonium
chloride are produced and must be removed from the reaction mixture.
Polysilazanes are suitable precursors for ceramic materials. Since most ceramic materials are produced by powder processing and sintering, near net shape forming is very difficult for complex
components.
Polysilazane-derived materials are a group of polymers and ceramics that can be functionalized to have a wide range of material properties such as electronic, magnetic, dielectric, and optical.
Polysilazane may also be converted into a black-colored, novel Silicon Carbon Nitride ceramic, which has potential use in high temperature and corrosive environment applications for MEMS.
Polysilazane, the crosslinked form of poly urea methyl vinyl silazane (PUMVS, Kion Corp.), is a novel hybrid organic/inorganic polymeric glass that is highly transparent in the infrared to ultraviolet Polysilazane microcomponents have potential applications in optical MEMS, and microfluidics.
Polysilazanes are useful among other things for the preparation of silicon nitride, Si3N4, by pyrolysis. Silicon nitride is a hard material and is useful in forming fibres for reinforcement of composite materials.
Micro- and macro-cellular SiCN and SiOCN foams were produced via two different routes by using a polysilazane preceramic polymer.
It has been recently demonstrated that preceramic polymers can be used to produce highly porous structures (foams, membranes, components with hierarchical porosity) of various compositions and morphologies
Polysilazanes are preceramic polymers primarily utilized for the preparation of silicon nitride for thermal shock resistant refractories and dielectric coatings for microelectronics
The manufacturing costs for polysilazane based coatings are comparable to those for sol-gel systems.
However, since the polysilazanes create much thinner layers, less material is used. In contrast, the complicated process of applying a silica coating using the CVD or PVD method is very cost intensive.
