Aluminum phosphide and magnesium phosphide are used in pest control; Aluminum phosphide, calcium phosphide, and zinc phosphide are used as rodenticides; Gallium phosphide and indium phosphide are used as semiconductors in the production of light-emitting diodes; [Ullmann]
Phosphides react with water to form the highly toxic and flammable phosphine; [Hawley] "Phosphides react quickly upon contact with moisture or acids to give the very toxic gas phosphine; phosphides also can react vigorously with oxidizing materials." [EPA] Phosphides are one of the four binary salts that have specific hazards (nitrides, carbides, hydrides, and phosphides); Phosphides give off phosphine gas, and a corrosive base is formed from contact with water. The corrosive base is the hydroxide of the metal that is attached to the phosphorus in the phosphide compounds; [Burke, p. 21] Substances not listed in the Phosphides category in Haz-Map include "Uranium phosphide," "Cadmium phosphide," and "Rare Earth Metals." See "Phosphine."
