(NH4)2HPO4 Ammonium Phosphate Dibasic White Or Colorless Crystal Powder
Chemical Formula NH4 2HPO4 Ammonium phosphate dibasic White Or Colorless Crystal Powder for Industrial
Product Description:
Diammonium hydrogen phosphate, also known as diammonium phosphate and commonly abbreviated as DAP, appears as colorless transparent monoclinic crystals or a white powder.
It has a relative density of 1.619 and a melting point of 190℃. It is readily soluble in water, and its aqueous solution is alkaline, with a 1% aqueous solution having a pH of 8.0 and a 0.1 mol/L solution having a pH of 7.8.
It is insoluble in alcohol and dimethyl ketone. When exposed to air, it gradually loses about 8% of its ammonia and converts into ammonium dihydrogen phosphate. It can react with ammonia water to form triammonium phosphate.
Features:
High-Efficiency Nitrogen-Phosphorus Compound Fertilizer (with 21% nitrogen and 53% phosphorus content), provides plants with water-soluble phosphorus and ammonium nitrogen. The fertilizer is high purity (more than 98%), completely soluble in water, and can be rapidly absorbed by plants.
It is free of substances harmful to crops, making it suitable for foliar spraying and drip irrigation. The pH value of this fertilizer ranges between 7.8 and 8.2, which plays an important role in regulating the pH balance of both soil and plant physiological cells.

Applications:
In the industrial sector, diammonium hydrogen phosphate (DAP) is extensively utilized as a fire retardant for textiles, wood, and paper. It is also employed as an additive in fire-resistant coatings.
For agricultural purposes, DAP serves as a high-efficiency, chlorine-free nitrogen-phosphorus compound fertilizer. Its rapid solubility in water aids in crop absorption, while its weakly alkaline properties effectively improve acidic soils.
