• Molecular Formula : (NH4)2HPO4
• Appearance : White Crystal
• CAS No : 7783-28-0
• HS No : 2835-29-9000
• White granulated crystals. Relative density: 1.803(19°C). Melting Point: 190°C. It is easy to soluble in water. When the temperature is higher than the melting point, it will Lost ammonia and water generate partial mixture of ammonium metaphosphate and phosphoric acid. Aqueous acid. (1% solution at PH = 7.8-8.2).
• Mainly used as timber, paper, fabric extinguisher, fire retardant coating additive, and dispersant for fibre processing and dyeing. DAP is a high effective compound fertilizer in agriculture. It provides the correct proportion of phosphate and nitrogen needed for farming wheat, barley and vegetables. It is applied in the early stage of fruit orchard fertilization. DAP also used as a fire-prevention agent for fabric, timber and paper.
