white crystals, non-toxic, fire-explosion-proof. Afraid of dampness.
It is used mainly as a fertilizer and for the manufacture of flame retardants and impregnations.
Monoammonium phosphate is well established as flame retardant. It is successfully used in extinguishing all classes of fires. The action is based on the fact that ammonium salts prevent combustion. As the temperature increases, the phosphate compounds become metaphosphoric acid, which is a compound in the likeness of glass. This acid envelops the surface of the materials with a protective layer that suppresses burning. This feature allows the use of phosphate compounds to extinguish wood materials, as well as oil and its derivatives, various gases and electrical appliances. In addition, monoammonium phosphate is completely soluble, which very well affects the ability to impregnate various materials - wood and woven.
Also available is Monoammonium phosphate fodder.

Technical monoammonium phosphate is a crystalline product with the formula NH₄H₂PO₄, supplied under technical specification. In documents it may also be designated as monoammonium phosphate tech grade or monoammonium phosphate. When purchasing, it is important to check the specification, the mass fraction of phosphorus calculated as P₂O₅, nitrogen content, moisture, lead and water-insoluble residue. For an enterprise, these parameters matter for incoming inspection and stable work with the batch.
Technical monoammonium phosphate and feed-grade monoammonium phosphate have a similar chemical basis, but are assessed against different requirements for purpose, impurities and accompanying documents. The technical grade is selected for production regulations, where the content of P₂O₅, nitrogen, moisture and insoluble residue matter. The feed specification is additionally focused on indicators important for feed raw materials. Therefore one grade cannot be substituted for the other based on the formula NH₄H₂PO₄ alone: the decision should be confirmed by the enterprise’s process engineer or laboratory.
Technical monoammonium phosphate dissolves well in water, but for a stable working solution it is introduced gradually, with stirring and concentration control. Under production conditions it is important to use a clean container, suitable water and exclude the ingress of foreign impurities. After dissolution, it is advisable to check the solution’s homogeneity, absence of sediment and compliance with the process chart parameters. If the raw material is used regularly, the solubility and moisture content of each batch should be tracked at incoming inspection.
Technical monoammonium phosphate is stored under conditions protected from wetting, in sealed factory packaging and with batch labelling preserved. On contact with moisture, the crystals can cake, become harder to dose and create difficulties when preparing solutions or dry mixtures. Bags are placed on pallets, avoiding contact with a wet floor, packaging damage and contamination of the raw material.
