Diammonium phosphate production declines, but the industry still has development potential

Diammonium phosphate refers to diammonium hydrogen phosphate, with the molecular formula (NH4) 2HPO4. It is an inorganic substance that appears as colorless and transparent monoclinic crystals or white powder. It is easily soluble in water, but insoluble in alcohol, acetone, and ammonia. Add water to make phosphoric acid from phosphate rock and sulfuric acid for heating pretreatment, add an appropriate amount of ammonia water to generate ammonium phosphate, and then add phosphoric acid for heating and evaporation to react with ammonium bicarbonate to generate diammonium phosphate.

The raw materials of diammonium phosphate are phosphate rock, sulfuric acid and sulfur. my country’s phosphate rock resources are widely distributed in 26 provinces across the country, and its resource reserves rank second in the world. According to data from the National Bureau of Statistics, my country’s phosphate rock production will reach 100 million tons in 2021, a year-on-year increase of 15.7%. As an important industrial raw material, the industry as a whole is operating well as sulfuric acid. According to statistics from the China Sulfuric Acid Industry Association, my country’s total sulfuric acid output will reach 110 million tons in 2021, a year-on-year increase of 5.8%, a record high. The output of phosphate rock, sulfuric acid, etc. continues to grow, ensuring sufficient supply of raw materials for diammonium phosphate in my country and providing guarantee for industry development.

Diammonium phosphate is often used in printing and platemaking, medicine, fire protection, electronic tubes and other fields. It is also used as feed additives, flame retardants, fire extinguishing agents and other ingredients in industry. In addition, diammonium phosphate is also a compound fertilizer containing nitrogen and phosphorus. It has a high concentration of active ingredients and is not easy to absorb moisture and agglomerate. It is suitable for crops that love nitrogen and require phosphorus, including vegetables, fruits, rice and wheat. In recent years, due to factors such as restrictions on national governance policies, shrinking local market demand, and declining production costs, my country’s diammonium phosphate output has shown a downward trend. According to statistics from the China Petroleum and Chemical Industry Federation, my country’s diammonium phosphate output in 2021 will reach 13.544 million tons, a year-on-year decrease of 4.4%.

According to the “2022-2027 Diammonium Phosphate Industry In-depth Market Research and Investment Strategy Analysis Research Report released by the Industrial Research Center, At present, my country’s phosphate fertilizer production ranks first in the world, and diammonium phosphate has long been exported to the international market as a representative product of phosphate fertilizer. According to statistics from the General Administration of Customs of China, my country’s diammonium phosphate exports reached 6.255 million tons in 2021, an increase of 522,000 tons compared with 2020, a year-on-year increase of 9.1%, and the export value of diammonium phosphate reached US$3.35 billion. India, Pakistan and Bangladesh are my country’s main importers of diammonium phosphate, and the above countries account for nearly 50.0% of my country’s total exports of diammonium phosphate.

Industry analysts said that diammonium phosphate has the advantages of good stability, long storage time, and non-volatility, and is used as a feed additive, Flame retardants and extinguishing agent auxiliary materials and fertilizer materials. my country is a large agricultural country with a vast area of ​​crop cultivation and a high demand for chemical fertilizers. As a high-concentration compound fertilizer, diammonium phosphate is suitable for various crops and soils, and the industry has huge development potential. However, my country’s diammonium phosphate production is currently on a downward trend. As environmental pollution problems are effectively controlled, the diammonium phosphate market will gradually pick up.
