Product Name:Dichlorosilane
English Name:Dichlorosilane
CAS No.:4109-96-0
Aliases:Trichlorosilane, Dichloromonosilane
Molecular Formula:Cl2H2Si
Physical Properties:Colorless gas with a characteristic odor. Density 1.22 g/cm3, melting point -122°C, boiling point 8.3°C, flash point -55°C, auto-ignition temperature 41-47°C. Relative density (water=1) 1.26, relative vapor density (air=1) 3.48, saturated vapor pressure 163.6 kPa (20°C), critical pressure 4.55 MPa, octanol/water partition coefficient 1.150, explosion limit 4.1%-96.0%. Soluble in most organic solvents such as benzene and diethyl ether; decomposes in water. Stable, incompatible with strong bases, water, alcohols, strong acids, strong oxidants and halogens; avoid humid air. Store in a cool, ventilated dedicated toxic gas warehouse, temperature not exceeding 30°C, away from fire and heat sources, sealed and moisture-proof, separated from oxidants, bases, alcohols and food chemicals.
Uses:Used in the electronics industry for epitaxial growth of polysilicon and chemical vapor deposition of silicon dioxide and silicon nitride; it is a key silicon source in the epitaxial process of semiconductor manufacturing. It is also employed for depositing silicon thin films in solar cell production and serves as a reducing agent and silylating agent in organic synthesis.
