Usage division
In the field of organic silicon materials:
As a ceramic precursor, silicon nitride can be converted into silicon nitride ceramic materials through high-temperature cracking and other processing methods. For example, polysilazane undergoes a series of complex chemical reactions at high temperatures, gradually removing small molecular substances and ultimately forming silicon nitride ceramics with excellent properties such as high strength, high hardness, high temperature resistance, and oxidation resistance, which can be used in the manufacturing of aerospace engine components, high-temperature furnaces, and so on.
Used for synthesizing polysilazane polymer materials: Silazane participates in polymerization reactions as a monomer, and the prepared polysilazane has a wide range of applications in coatings, adhesives, and other fields. For example, in some high-performance high-temperature resistant coatings, polysilazane can provide good heat resistance and chemical stability, allowing it to still protect the substrate in high-temperature environments.
In the field of semiconductors and microelectronics:
As an insulation layer material: Silicon nitride is deposited on the surface of semiconductor chips through processes such as chemical vapor deposition to form a silicon nitride insulation layer. In areas such as interlayer insulation and gate insulation of the chip, the insulation layer prepared from silicon nitride can effectively prevent current leakage, improve the performance and stability of the chip, and ensure the normal operation of electronic devices.
For surface passivation treatment: Silazane can form a protective film on the surface of semiconductor devices, reducing the influence of external environment on the devices, such as preventing the invasion of impurities such as water vapor and oxygen, extending the service life of semiconductor devices, and improving their reliability. It is commonly used in the manufacturing of microelectronic components such as integrated circuits and transistors.
In the field of surface treatment and coating:
Metal surface protection: Coating silicon nitride on the metal surface can form a protective film containing silicon nitrogen bonds, enhancing the metal's corrosion resistance, wear resistance, oxidation resistance and other properties. For example, using a silicon nitride coating on the surface of metal parts of car engines and metal shells of ships can significantly extend their service life and reduce maintenance costs.
Surface modification of glass and ceramics: Silazane can improve the hydrophilicity, hydrophobicity, hardness, and other properties of glass and ceramic surfaces. For example, after coating the surface of building glass with a silicon nitride coating, it can have self-cleaning, anti fog and other functions, improving the convenience and aesthetics of glass use.
In the field of catalysis:
As a catalyst carrier, materials derived from silazane have a large specific surface area and rich pore structure, which can be loaded with metal active components for various catalytic reactions. For example, in some organic synthesis reactions, silicon nitride materials loaded with metal catalysts can improve the selectivity and conversion rate of the reaction, such as catalyzing hydrogenation and oxidation reactions of olefins.
As a catalyst ligand, some silazanes can coordinate with metal ions to form complexes, which exhibit unique catalytic activity and participate in specific chemical reaction processes, promoting the smooth progress of the reaction.
