Silane : Description and use

Description

Silane is the silicon structural analogue of methane. It gives its name to silanes, chemical compounds with the SinH₂n+2 formula. It belongs to the family of hydrides made up of silicon and hydrogen, which can be considered the silicon analogues of alkanes.
It is a colourless, pyrophoric gas, with an unpleasant odour.

Flammability: This product is flammable when in contact with air.

USE
  • To manufacture pure silicon.
