Description and Uses

Ammonium phosphates include mono- and diammonium orthophosphates and ammonium polyphosphates. As discussed below, these are made directly by reaction anhydrous ammonia with orthophosphoric acid or superphosphoric acid. Both are dry crystalline materials with good handling properties.

It is commonly used in fertilizer as plant food as well as a yeast nutrient. Ammonium phosphate dibasic has been used to prepare multi-shell nanoparticles to increase transfection efficiency.
