Ammonium phosphate is a broad generic name for a variety of fertilizer materials containing both nitrogen and phosphate. Another way to prevent getting this page in the future is to use Privacy Pass. Il est également employé comme retardateur de flamme dans la composition des thermoplastiques, celle des panneaux de particules bois ( Agglo, Medium) et celle des retardants permettant aux pompiers de freiner l'avancée des flammes lors d'un incendie[2]. Ammonia contains one nitrogen and three hydrogens opposed to one nitrogen and four hydrogens formed by ammonium. Ammonium phosphate is an unstable compound made of ammonium and phosphate salt with the chemical formula (NH4)3PO4. Les autres sels d'ammoniac et d'acide phosphorique existent également : phosphate de diammonium (NH4)2HPO4 et phosphate de monoammonium NH4H2PO4. Ammonium phosphate adds nitrogen and phosphates to the lawns which lack the nutrients. In the other side, it is ionized to ammonium. It is elusive, and of little economic interest due to its uncertainty. La dernière modification de cette page a été faite le 8 septembre 2019 à 08:25. Some major distinctions between the two is that Ammonia gives off a heavy odour while Ammonium does not smell at all. The production of the ammonium phosphate (NH 4 H 2 PO 4) takes place by the process of reacting phosphoric acid (H 3 PO 4) with the anhydrous ammonia (NH 3): NH 3 + H 3 PO 4 → NH 4 H 2 PO 4 On le désigne également par le sigle ADP, de l'anglais Ammonium Dihydrogen Phosphate. The chemical formula of Ammonium Phosphate is given as (NH4)3PO4. Compare Products: Select up to 4 products. Ammonium phosphate readily undergoes decomposition reaction emitting very toxic fumes. USA; Globally; Search term: "ammonium phosphate*" Product Category: Research Essentials: Essential Chemicals. Sometimes, it can also be formed while adding an excess amount of ammonia along with acid phosphate whose chemical formula is (NH4)2HPO4. Il se forme à l'état de poudre cristalline lorsqu'on mélange deux solutions concentrées d'ammoniac et d'acide phosphorique : Il est soluble dans l'eau, et la solution aqueuse de phosphate d'ammonium libère de l'ammoniac lorsqu'on la chauffe. • Il s'agit d'un sel d' ammoniac NH 3 et d' acide phosphorique H 3 PO 4 , constitué de cations ammonium NH 4 + et d' anions phosphate PO 4 3– . Il s'agit d'un sel d'ammoniac NH3 et d'acide phosphorique H3PO4, constitué de cations ammonium NH4+ et d'anions dihydrogénophosphate H2PO4. Structure and Formula. The chemical formula of Ammonium Phosphate is given as (NH4)3PO4. • Ammonium phosphate is a high source of elemental nitrogen used as an ingredient in certain fertilizers. Ils peuvent être convertis l'un en l'autre avec le phosphate d'ammonium en ajoutant davantage d'ammoniac ou d'acide phosphorique selon les besoins.
