Aluminium phosphide is a highly toxic inorganic compound with the chemical formula AlP, used as a wide band gap semiconductor and a fumigant. This colorless solid is generally sold as a grey-green-yellow powder due to the presence of impurities arising from hydrolysis and oxidation .
Aluminium phosphide tablets. Aluminium phosphide poisoning is poisoning that occurs as a result of excessive exposure to aluminium phosphide (AlP), which is readily available as a fumigant for stored cereal grains and sold under various brand names such as QuickPhos, Salphos and Celphos. Aluminium phosphide is highly toxic, especially when ...
The tablets or pellets (usually aluminium, calcium or magnesium phosphide for fumigation/gassing) may also contain other chemicals which evolve ammonia, which helps reduce the potential for spontaneous combustion or explosion of the phosphine gas. [citation needed]
Aluminium phosphate is a chemical compound. In nature it occurs as the mineral berlinite. [3] Many synthetic forms of aluminium phosphate are known. They have framework structures similar to zeolites and some are used as catalysts, ion-exchangers or molecular sieves. [4] Commercial aluminium phosphate gel is available.
Aluminium gallium phosphide, (Al,Ga)P, a phosphide of aluminium and gallium, is a semiconductor material. It is an alloy of aluminium phosphide and gallium phosphide . It is used to manufacture light-emitting diodes emitting green light.

An example of a group 1 phosphide is sodium phosphide (Na 3 P). Other notable examples include aluminium phosphide (AlP) and calcium phosphide (Ca 3 P 2), which are used as pesticides, exploiting their tendency to release toxic phosphine upon hydrolysis. Magnesium phosphide (Mg 3 P 2) also is moisture sensitive.
