Product Description

Si2H6 gas is known as disilane, which is an inorganic compound composed of silicon (Si) and hydrogen (H). Disilane has the chemical formula Si2H6 and is a member of the silane family of compounds. Here are some key points about disilane gas:

1. Structure and Properties: Disilane consists of two silicon atoms bonded together with six hydrogen atoms. It is a colorless gas with a pungent odor. Disilane is highly reactive and can spontaneously ignite in the presence of air or oxygen.

2. Synthesis and Production: Disilane can be synthesized by various methods, including the reaction of silicon powder with hydrogen gas at high temperatures or through the hydrolysis of silicon-derived precursors. It is typically produced and used in a controlled environment due to its reactivity and flammability.

3. Applications:

   • Semiconductor Industry: Disilane is used in the production of silicon-based thin films, specifically for the deposition of high-quality silicon films in the semiconductor industry. It serves as a precursor for the formation of silicon layers in processes such as chemical vapor deposition (CVD) and atomic layer deposition (ALD).

   • Solar Cells: Disilane is employed as a precursor gas in the fabrication of silicon thin-film solar cells. The deposition of amorphous silicon films using disilane enables the production of low-cost and flexible solar cell devices.

   • Chemical Synthesis: Disilane can be used as a reducing agent or as a source of silicon in various chemical reactions. It finds applications in the synthesis of organosilicon compounds, silicon-based polymers, and other silicon-containing materials.

4. Safety Considerations: Disilane is highly flammable and can form explosive mixtures with air. It is also toxic and can cause severe burns upon contact with the skin or eyes. The gas should be handled with extreme caution, and appropriate safety measures, such as proper ventilation and personal protective equipment, should be followed.

Disilane gas, while highly reactive and hazardous, has important applications in the semiconductor industry and the production of silicon-based materials. It plays a role in the development of advanced electronic devices and renewable energy technologies.
