1, monoammonium phosphate is soluble in water, soluble in acid, insoluble in organic solvents.
2, in the air will deliquesce and change into ammonia and phosphate containing several different oxidation levels.
3, monoammonium phosphate is a weakly acidic salt that can react with bases.

1. Firefighting field
1) Fire extinguishing agents

2) Flame retardant
Ammonium dihydrogen phosphate, as a basic raw material for the preparation of new type of excellent inorganic flame retardant ammonium polyphosphate or composite flame retardant, has a good application in the field of flame retardant. Using ammonium dihydrogen phosphate and urea as raw materials, after foaming, polymerisation and curing to get I-type ammonium polyphosphate products, the product polymerisation degree is 52.08, the ammonia nitrogen and effective phosphorus mass fraction to meet the national standards, respectively, 14.32% and 69.53%, flame retardant rate of 49.94%.

2. Material field
1) Glass materials

2) Lithium battery
Lithium iron phosphate material has become the preferred cathode material for lithium-ion power batteries and a hot spot for new energy research in various countries due to its simple preparation process, long product cycle life, high temperature stability, low cost and high safety performance.
