Disilane, with the chemical formula Si2H6, is a colorless, flammable gas that is often used in semiconductor manufacturing and other specialized applications. Here are some key characteristics of disilane:
Physical Properties:
Appearance: Colorless gas.
Boiling Point: -111.9 °C.
Melting Point: -185 °C.
Density: 1.11 g/L at STP (Standard Temperature and Pressure).
Solubility: Slightly soluble in water.
Chemical Properties:
Reactivity: Highly reactive and can spontaneously ignite in air due to the exothermic reaction with oxygen.
Decomposition: Upon heating or upon contact with moisture, it decomposes to form silicon and hydrogen gas.
Uses:
Semiconductor Industry: Disilane is primarily used in the deposition of amorphous silicon films and polysilicon layers in semiconductor devices.
Research: It serves as a reagent in chemical research and synthesis.
Coatings: It can be used in the production of thin film coatings for optical and electronic applications.
Safety Concerns:
Flammability: Disilane is extremely flammable and can be explosive in air.
Toxicity: It can be toxic if inhaled, and exposure may cause irritation of the eyes, nose, and throat.
Corrosivity: It can react violently with oxidizers and strong acids.
When it comes to suppliers of disilane, you should look for reputable chemical manufacturers or distributors that specialize in high-purity gases and chemicals for industrial and laboratory use.
