Introduction of Ammonium Dihydrogen Phosphate
Ammonium dihydrogen phosphate, also known as monoammonium phosphate, is a white crystal. Its chemical formula is NH4H2PO4. It can be decomposed into ammonium metaphosphate (NH4PO3) by heating. It can be prepared by reaction of ammonia water and phosphoric acid. It is mainly used as a fire retardant for fertilizers and wood, paper and fabrics, and also as a pharmaceutical and ruminant feed additive.
