What is Diammonium Hydrogen Orthophosphate?

Diammonium Hydrogen Orthophosphate is a type of inorganic phosphate, specifically the diammonium salt of phosphoric acid. This commercially available fertilizer is commonly known as diammonium phosphate or DAP and has an analysis of 18-46-0 (N-P2O5-K2O). Its main function is to serve as a fertilizer. DAP is an ammonium salt and falls under the category of inorganic phosphates.

Diammonium hydrogen ortho phosphate belongs to a group of water-soluble ammonium phosphate salts that can be produced by reacting ammonia with phosphoric acid until the desired pH is reached. The resulting DAP settles in the solution and is subsequently separated by centrifugation to obtain a crystalline powder form. The manufacturing process of Diammonium Phosphate involves the reaction of anhydrous ammonia with phosphoric acid in a reactor, resulting in a partially reacted slurry containing both monoammonium phosphate and diammonium phosphate. This process is employed to produce granular diammonium phosphate (DAP).

Properties of Diammonium Hydrogen Orthophosphate

Di-Ammonium Hydrogen Phosphate (DAP) has several notable properties:

Chemical Composition

Diammonium Hydrogen Ortho phosphate has the chemical formula (NH4)2HPO4. It is composed of two ammonium ions (NH4+) and one hydrogen phosphate ion (HPO42-).


Diammonium Hydrogen Orthophosphate is highly soluble in water. This property makes it easily dissolved and readily available for plant uptake when used as a fertilizer.


DAP is slightly acidic in nature. When dissolved in water, it can lower the pH of the solution, which can be beneficial for certain crops that prefer acidic conditions.

Nutrient Content

It is a rich source of nitrogen (N) and phosphorus (P). It typically contains 18% nitrogen and 46% phosphorus pentoxide (P2O5). These nutrients play crucial roles in plant growth, development, and overall health.

Fertilizer Efficiency

DAP has high nutrient availability, meaning that plants can easily absorb and utilize the nitrogen and phosphorus it provides. This makes it an effective fertilizer for promoting healthy root development, enhancing flowering and fruiting, and improving overall crop yield.

Physical Form

Diammonium Hydrogen Ortho phosphate is commonly found in the form of granules or crystalline powder. These forms allow for easy application and mixing with other fertilizers or soil amendments.


DAP is relatively stable under normal storage and handling conditions. However, it is important to store it in a dry place to prevent moisture absorption and caking.

Safety Considerations

Diammonium Hydrogen Orthophosphate is generally safe to handle and use when following recommended guidelines. However, like any fertilizer, it should be stored out of reach of children and pets and handled with care to avoid eye or skin contact.

Diammonium Hydrogen Orthophosphate Applications

Diammonium Hydrogen Orthophosphate finds extensive applications across various industries:

  1. Fertilizers: Diammonium Hydrogen Ortho phosphate is widely utilized in the manufacturing of fertilizers. Its high nitrogen and phosphorus content make it an effective nutrient source for promoting plant growth and enhancing crop yields.
  2. Sugar Purification: DAP is employed in the sugar industry as a purifying agent. It aids in the removal of impurities and helps improve the quality of refined sugar.
  3. Yeast Cultures: Di Ammonium Hydrogen Ortho phosphate is used in the cultivation of yeast. It provides essential nutrients for yeast growth, ensuring optimal fermentation processes in various industries such as baking, brewing, and winemaking.
  4. Soldering Flux: Diammonium Hydrogen Orthophosphate serves as a flux in soldering applications involving tin, copper, brass, and zinc. It helps in the soldering process by facilitating the flow of molten metal and promoting proper adhesion to the surfaces being joined.
  5. Dentifrices and Corrosion Inhibitors: Diammonium Hydrogen Orthophosphate is utilized in the formulation of dentifrices (toothpaste) and corrosion inhibitors. Its inclusion in these products helps prevent dental issues and protect metal surfaces from corrosion.
  6. Fire Retardant: Diammonium Hydrogen Orthophosphate can act as a fire retardant. It is employed in various industries to enhance the fire resistance of materials. It finds applications in fireproofing textiles, paper, wood, and vegetable fibers.
  7. Impregnating Lamp Wicks and Match Afterglow Prevention: Diammonium Hydrogen Orthophosphate is used to impregnate lamp wicks, improving their burning characteristics. Additionally, it helps prevent afterglow in matches, ensuring they extinguish promptly after use.

Diammonium Hydrogen Orthophosphate’s versatile properties make it a valuable component in several industrial processes, ranging from agriculture and manufacturing to fire safety and preservation.
