Product Description

Product Description

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

1. Structure: Silane has a tetrahedral molecular structure, with the silicon atom at the center and the four hydrogen atoms bonded to it.

2. Properties: Silane is a colorless, flammable gas with a pungent odor. It is less dense than air and can form explosive mixtures with air when exposed to certain conditions. Silane is highly reactive and can spontaneously ignite in the presence of oxygen.

3. Production: Silane can be produced through various methods. One common method is the reaction of metallurgical-grade silicon with hydrogen gas at high temperatures. Other methods involve the hydrolysis of silicon halides or the reduction of silicon compounds.

4. Applications: Silane finds applications in several industries:

   • Semiconductor Industry: Silane is a key precursor gas used in the deposition of silicon-based thin films, such as silicon dioxide (SiO2) and amorphous silicon (a-Si), in the manufacturing of integrated circuits and thin-film transistors.

   • Solar Energy: Silane is used as a precursor gas in the production of silicon-based solar cells. It is involved in the deposition of silicon layers that form the active photovoltaic material.

   • Chemical Industry: Silane derivatives are used as coupling agents, surface modifiers, and cross-linking agents in various chemical processes. They can improve adhesion, modify surface properties, and enhance the performance of coatings, adhesives, and sealants.

   • Nanotechnology: Silane is utilized in nanofabrication processes, such as the functionalization of nanoparticles or the modification of nanoscale surfaces.

It's important to note that silane is a highly reactive and potentially hazardous compound. Due to its flammability and reactivity, proper safety precautions should be followed when handling, storing, or using silane.
