Ammonium Phosphate Dibasic

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.

Product Usage

Ammonium Phosphate Dibasic (DAP) is a versatile compound fertilizer containing both nitrogen and phosphorus, as well as a vital industrial additive. In agriculture, it is one of the most preferred high-concentration composite fertilizers; its water-soluble and physiologically neutral nature makes it suitable for most crops and soils, significantly promoting root development and early maturity. In the industrial sector, DAP serves as an excellent flame retardant, widely used in the fireproof treatment of wood, paper, and textiles, and in the formulation of dry powder extinguishing agents. Additionally, in the food industry, it is commonly used as a fermentation assistant and dough conditioner, while also playing a key role in printing plate making and pharmaceutical manufacturing.
