Because of its instability, it is an elusive and of no commercial value (except for scientific research). In addition to (NH4)3PO4, a related double salt (NH4)3PO4.(NH4)2HPO4 is also recognized. It too is unstable. The instability of these salts results of their facile decomposition with evolution of ammonia:〔Klaus Schrödter, Gerhard Bettermann, Thomas Staffel, Friedrich Wahl, Thomas Klein, Thomas Hofmann "Phosphoric Acid and Phosphates" in ''Ullmann’s Encyclopedia of Industrial Chemistry'' 2008, Wiley-VCH, Weinheim. 〕 :(NH4)3PO4 → H(NH4)2PO4 + NH3 In contrast to the fragile nature of the triammonium salts, diammonium phosphate (H(NH4)2PO4) is a valuable material, mainly used as a fertilizer. ==See also== * Ammonium polyphosphate * Monoammonium phosphate * Diammonium phosphate 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ammonium phosphate」の詳細全文を読む スポンサード リンク
