Silane Information |
A. Appearance
Silane, SiH4, is also called silicon tetrahydride, silicane
and monosilane. Silane is a colorless, flammable gas with a repulsive
odor.
B. Physical Properties of SiH4
Molecular mass: 32.1179 g/molC. History
melting point -185 oC
boiling point -111.8 oC
D. Natural Abundance
Silane does not occur in nature.
E. Industrial Production
Tetrahalosilanes,
such as SiCl4, are reduced to SiH4
by hydrides such as LiH, NaH, or LiAlH4.
F. Industrial Uses
Silane is used to produce ultra-pure silicon for use in the semiconductor
applications.
G. Gas Density of SiH4
The density of SiH4 is 1.3128 g/L at 25 oC
and 1 atm. This is 11% more dense than air.
H. Gas Solubility of SiH4
Silane is insoluble in water and most organic solvents.
