Does not contain
nitrates and chlorine. It is applied on all types of soils, under all cultures.
Obtained in a single process by neutralizing phosphoric acid with excess
ammonium.
Diammonium
phosphate (disubstituted ammonium phosphate) is a salt of orthophosphoric acid.
The second most stable ammonium phosphate.
Physical characteristics:
At 70 oC loses
ammonia and turns into monoammonium phosphate (NH4H2PO4).
Dissociation pressure at 100 ° C - 5 mm Hg.
At 20 ° C in 100
g of water dissolves 71 g of substance.
The acidity of
the monomolar solution is 8.0.
It has low
hygroscopicity.
Appearance is produced in the diammonium phosphate industry, depending on the brand: white crystals or the same crystals, but with a yellowish or gray tinge. Contains phosphorus oxide (V) 50-52%, ammonia is 23-23.5%. Mass fraction of moisture is 4-5%.
Diammonium phosphate
fertilizer contains 18% nitrogen, total phosphates 46%, water 1.8%. Appearance:
granules without impurities, from white with a yellow tinge to dark gray, less
than 6 mm in diameter. The flowability of the substance is 100%.
