Enhance soil fertility and plant growth with Diammonium hydrogen phosphate NH4 2HPO4 CAS No. 7783-28-0
Product Description:
Diammonium hydrogen phosphate, also known as diammonium phosphate and commonly abbreviated as DAP, is a substance that occurs as colorless transparent monoclinic crystals or a white powder.
This chemical compound has a relative density of 1.619 and a melting point of 190℃. It exhibits a high solubility in water, resulting in an alkaline aqueous solution. A 1% aqueous solution has a pH of 8.0, while a 0.1 mol/L solution shows a pH of 7.8. Conversely, DAP is insoluble in alcohol and dimethyl ketone.
When exposed to air, DAP undergoes a gradual loss of approximately 8% of its ammonia content, leading to the conversion into ammonium dihydrogen phosphate. Additionally, it has the capability to engage in reactions with ammonia water, resulting in the formation of triammonium phosphate.
Features:
High-Efficiency Nitrogen-Phosphorus Compound Fertilizer contains 21% nitrogen and 53% phosphorus content. This fertilizer supplies plants with water-soluble phosphorus and ammonium nitrogen. It is a high purity product with more than 98% purity, making it completely soluble in water and easily absorbed by plants.
Free of harmful substances to crops, this fertilizer is suitable for foliar spraying and drip irrigation. Its pH value falls between 7.8 and 8.2, allowing it to effectively regulate the pH balance of both soil and plant physiological cells.
