Silane Uses

Silane, a compound of silicon and hydrogen, is a general term for a range of compounds, including monosilane (SiH4), disilane (Si2H6), and some of the more advanced silicon hydrides. Currently, the most widely used is monosilane. Generally, monosilane is referred to as silane.

The use of silanes as silicon-containing films and coatings has expanded from the traditional microelectronics industry to steel, machinery, chemical and optical fields. The silicon coating can increase the high-temperature oxidation resistance of ordinary steel to more than 100,000 times, can greatly improve the high-temperature chemical stability of other metals, can significantly enhance the corrosion resistance of the internal combustion engine blades, so that various materials and parts are The bond strength between the two is greatly increased, the life of the automobile engine parts is prolonged, and the reflection and transmission properties of the glass can be changed, thereby achieving significant energy saving and decorative effects. The bond strength between various materials and parts can be greatly improved, the life of the automobile engine parts can be prolonged, and the reflection and transmission properties of the glass can be changed, thereby achieving significant energy saving and decorative effects. In the production process of float glass, a layer of light reflecting layer is coated on the surface of the glass with silane, and the adhesion is extremely strong. It does not fade under long-term sunlight, and the light transmittance is only 1/3 of ordinary glass; The large-area polycrystalline silicon battery (BSNSC) coated with silicon nitride has reached a high efficiency of 15.7%. The use of various silicon-containing films fabricated by silane vapor deposition is still increasing in high technology.

A potential application for silanes is the manufacture of high-performance ceramic engine parts, in particular, using the silane to produce silicide (Si3N4, SiC, etc.) fine powder has received increasing attention. The United States, Japan, and other countries are spending billions of dollars to develop high-temperature resistance, high-strength, high-chemical stability ceramics by using silicon, silicon nitride and silicon carbide micro powder. The micro power prepared by the silane gas phase reaction method has the highest purity, and the particles are fine and uniform, which can greatly improve the performance of the ceramic parts. Its applications are extremely broad, for example, it has been put into practical use in automotive engine valves and turbocharger rotors, and it has been commercialized in high-speed bearings and high-performance tools. When being used in internal combustion engines, the operating temperatures can be increased to 1400 ° C, greatly improving the efficiency of the heat engine, and it is suitable for a variety of fuels. Also, it can extend the service life;

Silane chemistry application
1. High-purity silane is used together with high-purity ammonia gas to produce solar thin-film cells to attach silicon molecules to the surface of the battery.
2. It is used together with high-purity ethylene for the production of LOW-E coated glass.
3. High-purity silane is used as a silicon source in epitaxial growth processes for large-scale integrated circuits.
4. It is used in research, development, production of national defense and military industries.
