Use
Silicon tetrahydride is a colorless, flammable and poisonous gas, with a strong repulsive odor. Silicon tetrahydride 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. Silicon tetrahydride is lighter than air. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. Silicon tetrahydride is used in the production of amorphous silicon.
