Silane SIH4 Gas

Application

Silane is used

◇ in the production of special glasses to provide a reflective coating

◇ as a source of silicon for growing polycrystalline and epitaxial (monocrystalline) silicon, silicon dioxide, silicon nitride and doping of gallium arsenide

◇ as a dopant in the production of compound semiconductor devices, for chemical vapour deposition of refractory metal silicides, and for deposition of amorphous silicon on photocopier drums

◇ in the production of photovoltaic cells

◇ in the production process of optical fibres

……

Process

Silane is produced by the reduction of silicon tetrachloride by metal hydrides such as lithium or calcium aluminum hydride.

Silane is produced by treatment of magnesium silicide with hydrochloric acid.
