ABSTRACT
Molecular formula: Mg3P2 Synonyms and trade names: Magnesium phosphide; Magtoxin (R); Fumi-Cel (R); FumiStrip (R)
Magnesium phosphide and Magtoxin have not been reported as ammable chemical substances. However, they react readily with water to produce hydrogen phosphide (phosphine, PH3) gas, which may ignite spontaneously in air. Magnesium phosphide is stable to most chemical reactions, except for hydrolysis. Magtoxin, Fumi-Cel, and Fumi-Strip will react with moist air, liquid water, acids, and some other liquids to produce toxic and ammable hydrogen phosphide gas. Magnesium phosphide is more reactive than aluminium phosphide and will liberate hydrogen phosphide more rapidly and more completely at lower temperatures and humidities. Magnesium phosphide is not combustible but forms ammable gas on contact with water or damp air. Magnesium phosphide gives off irritating or toxic fumes (or gases) in a re and on contact with water or damp air may cause explosion hazard.
