CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Silane is a colorless, flammable and poisonous gas, with a strong repulsive odor. It is easily ignited in air, reacts with oxidizing agents, is very toxic by inhalation, and is a strong irritant to skin, eyes and mucous membranes. Silane is lighter than air. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. It is used in the production of amorphous silicon. |
