Product Description of Diammonium Phosphate CAS#7783-28-0

Ammonium phosphates mainly include monoammonium orthophosphate, diammonium orthophosphate and ammonium polyphosphate. They are produced by the direct reaction of anhydrous ammonia with orthophosphoric acid or superphosphoric acid. These products are dry crystalline solids with good handling performance, facilitating convenient storage, transportation and industrial processing.


Product Application of Diammonium Phosphate CAS#7783-28-0

Diammonium phosphate is widely used as a high-efficiency compound fertilizer for vegetables, fruits, rice and wheat, providing both nitrogen and phosphorus nutrients. It also serves as a feed additive for livestock and ruminants, as well as a yeast nutrient and water softener. In industrial and laboratory applications, it is used as an analytical reagent and buffer agent, and applied in printing plates, pharmaceuticals and electronic components. In the food industry, it acts as a leavening agent, dough conditioner, fermentation additive and pH regulator. Furthermore, industrial-grade diammonium phosphate is utilized in flame retardant formulations, dry powder fire extinguishers, wood and fabric impregnation, fluorescent phosphors, wastewater treatment, as well as special fireproof and military thermal insulation materials.
