CAS No 20859-73-8
Application / Uses Preparation Aluminium phosphide (AlP) is an inorganic compound used as a wide band gap semiconductor and a fumigant. This colourless solid is generally sold as a grey-green-yellow powder due to the presence of impurities arising from hydrolysis and oxidation.
Application / Uses Preparation Sodium phosphide, Na3P, is a black, ionic salt containing the alkali metal sodium and the phosphide anion. Na3P is a source of the highly reactive phosphide anion. It should not be confused with sodium phosphate, Na3PO4.
Application / Uses Preparation Metal phosphides have been used as rodenticides. A mixture of food and zinc phosphide is left where the rodents can eat it. The acid in the digestive system of the rodent reacts with the phosphide to generate the toxic phosphine gas.
