High Nutrient Content Diammonium Phosphate DAP Fertilizer with Corrosion Resistant and Fire Retardant Properties

Diammonium Phosphate (DAP) is a highly efficient nitrogen-phosphorus compound fertilizer and a significant industrial raw material, renowned for its high nutrient content, excellent physical properties, and wide range of applications.

• Aliases: DAP
• English Name: Diammonium Phosphate
• Chemical Formula: (NH₄)₂HPO₄
• Molecular Weight: 132.06
• CAS Number: 7783-28-0

High nutrient content (N & P₂O₅), good granular strength, low hygroscopicity, and slight alkalinity.

• Used as a primary base fertilizer for a wide range of crops such as wheat, corn, and fruits
• Its slightly alkaline nature makes it particularly suitable for neutralizing acidic soils

• Acts as an effective intumescent flame retardant in wood, textiles, and coatings
• A key component in ABC dry chemical fire extinguishers

• Serves as a source of nitrogen and phosphorus in microbial fermentation processes
• Functions as a buffering agent in cell culture media and fermentation broths

• Used as a flux in soldering and metalworking to remove oxides
• Acts as a corrosion inhibitor in water treatment systems and cooling towers

• Advanced granulation processes produce hard, uniform, and dust-free granules
• Implementation of real-time near-infrared (NIR) spectroscopy for online monitoring

• Development of controlled-release or stabilized DAP formulations
• Implementation of advanced scrubbing systems in production plants

• Modern DAP plants utilize energy-efficient processes
• Efforts to source phosphoric acid with lower levels of potentially toxic elements

• Rigorous quality control ensures consistent nutrient content
• Products are routinely analyzed for low levels of heavy metals

• Nitrogen (N) Content: 18% minimum
• Phosphorus (P₂O₅) Content: 46% minimum
• Water Soluble P₂O₅: Typically >90% of total phosphorus

• Appearance: Typically grey or off-white, spherical granules
• Solubility: Soluble in water; the solution is slightly alkaline (pH approximately 7.8-8.2)
