Product Description

Silane (SiH4) is a chemical compound consisting of one silicon atom bonded to four hydrogen atoms. Here are some key points about silane:

1. Chemical Formula: SiH4
2. Molecular Weight: 32.12 g/mol
3. Structure: Silane has a tetrahedral molecular geometry, with the silicon atom at the center and four hydrogen atoms arranged around it.
4. Physical Properties: Silane is a colorless, flammable gas with a pungent odor. It is less dense than air and can form explosive mixtures when combined with air.
5. Chemical Reactivity: Silane is highly reactive and can readily react with oxygen, water, and other substances. It is pyrophoric, meaning it can ignite spontaneously in the presence of air or moisture.
6. Applications: Silane has various applications across different industries. In the semiconductor industry, it is used as a precursor in the chemical vapor deposition (CVD) process to deposit thin films of silicon onto semiconductor substrates. Silane is also used in the production of solar cells, optical fibers, and certain types of coatings. It can be used as a reducing agent in organic synthesis and as a source of silicon in the synthesis of various silicon-containing compounds.
7. Safety Considerations: Silane is highly flammable and poses fire and explosion hazards. It is also toxic and can cause chemical burns. Proper safety precautions, including the use of specialized equipment and trained personnel, should be followed when handling and working with silane.
8. Storage and Handling: Silane is typically stored and transported in specialized containers under controlled conditions to prevent exposure to air and moisture. It is handled with extreme caution due to its reactivity and flammability.
9. Environmental Impact: Silane is not considered a significant environmental hazard. However, its use and disposal should be in accordance with local regulations and best practices to minimize any potential impact.
10. Silanes as Functional Groups: Silanes can also refer to a broader class of compounds that contain a silicon atom bonded to organic groups (R-SiR3). These silane compounds have various applications, including as coupling agents and surface modifiers in materials science and as protective coatings.
