Description
A gas with a repulsive odor. Silane gas (SiH4) is used to the manufacture of semiconductors and in the manufacture of amorphous Silica. The name silane is also used for a series of silicon hydride compounds, analogous to paraffin hydrocarbons, and having the general formula (Si)n(H2)n+2. Silanes are inherently unstable but have the unique ability to bind organic polymers to inorganic substrates. They have been used in the consolidation of Masonry, Adobe, and Stone.
Synonyms and Related Terms
silicon tetrahydride; silicane; monosilane; silano (Esp.); silane (Fr.); silano (It.); silano (Port.)
Risks
Dangerous fire risk; ignites spontaneously. Liquid can cause frostbite. Toxic by inhalation.
Airgas: SDS
