Manufacturing Process

Our Diammonium Phosphate is synthesized using thermal-process phosphoric acid, which distinguishes it from wet-process alternatives commonly used in fertilizer production. The thermal process involves:

  • High-temperature treatment of elemental phosphorus
  • Precise neutralization with ammonia under controlled conditions
  • Advanced purification steps to eliminate impurities
  • Stringent quality control throughout production

This manufacturing method results in a product with exceptional purity, minimal heavy metal content, and consistent performance characteristics.
