, also known as urea phosphate salt, is a kind of phosphate compound with amino acid structure formed by the reaction of equal moles of phosphoric acid and urea. It is colorless transparent prismatic crystal in appearance, soluble in water, but insoluble in ether, toluene, carbon tetrachloride. The aqueous solution is acidic and the PH value of 1% aqueous solution is 1.89. it has a molecular weight of 158.06, a density of 1.74g/cm³, a melting point of 115-117℃.
Urea phosphate is a ruminant fee additive that is superior to urea and can provide both non-protein nitrogen and phosphorus. It is also a high concentration of nitrogen and phosphorus compound fertilizer, which is suitable for alkaline soil. Urea phosphate salt has a good effect on the growth of crops, which can not only ensure the normal growth of plants, but also have negative impact on the soil.

Urea Phosphate Uses
- Efficient fertilizer. High concentration nitrogen and phosphorus compound fertilizer. It is an unstable complex that can dissolve into urea and phosphoric, and can release a small amount of CO2 and NH3 when it is buried in the soil. Therefore, urea phosphate applied into soil ad fertilizer and saline-alkaline soil improver can reduce the PH value of soil or soil micro-area, improve the acid-base balance of the soil. Thus, it can improve soil physical and chemical properties, improve soil structure and promote the growth of crops.
- Feed additive. It can used as a non-protein nitrogen feed additive for ruminants such as cattle and sheep. It can not only supplement the nitrogen and phosphorus necessary for animal growth, increase the physiological metabolism of animals, but also has the effect of increasing milk on ruminants, as well as the effect of increasing hair, weight, milk volume and quality.
- Silage preservative. With excellent silage preservation effect, it is a good preservative for melons, vegetables and silage for forage.
Fire retardant cleaner, flame retardant, powder extinguish agent, high temperature adhesive. It can also prepare ammonium polyphosphate intermediate.
Urea Phosphate Fire Retardant
Ammonium polyphosphate with the decomposition temperature more than 200℃ is a widely used flame retardant. After the treatment of urea phosphate aqueous solution, the wood laminate doesn’t deform, the surface of wood products won’t fire when the temperature is in 210℃. Meanwhile, it doesn’t affect the adhesive strength between laminates. It can be used for the fire retardant treatment of wood fiber products, cotton fiber products and resins. In addition, it can also be used to produce refractory coatings, fireproof cleaning agents and granular fire extinguishing agents.
