It is a wide band gap semiconductor and is used as a rodenticide, insecticide and fumigant for stored cereal grains. Aluminum is the most abundant metal in the earth's crust and is always found combined with other elements such as oxygen, silicon, and fluorine.  Metal phosphides are hydrolysed to phosphine upon contact with water or stomach acid. Phosphine is a colorless, flammable, explosive, and toxic gas. (L980, L739, L740, L770)"}]
