(NH4)2HPO4 A salt of ammonia and phosphoric acid that forms white monoclinic crystals, which are soluble in water; used as a fertilizer and fire retardant.

Ammonium Phosphate


(in Russian, ammofos), double ammonium-phosphate concentrated mineral fertilizer. It is composed principally of monoammonium phosphate (NH4 H2 PO4) with an admixture of diammonium phosphate [(NH4)2 HPO4 ]. It contains 45–52 percent phosphoric anhydride and 10–12 percent nitrogen. It is used on various soils as a fundamental or supplementary fertilizer.
