  • Ammonium phosphate - Wikipedia

    Ammonium phosphate is an ammonium salt of orthophosphoric acid. It is a highly unstable compound with the formula (NH 4) 3 PO 4. Because of its instability, it is elusive and of no commercial value. A related "double salt", (NH 4) 3 PO 4. (NH 4) 2 HPO 4 is also recognized but is too unstable for practical use. Both triammonium salts evolve ammonia. In contrast to the unstable nature of the ...

    01.05.1991  Struvite, an important reaction product in magnesium ammonium phosphate cement systems, was synthesized in the laboratory. The elevated-temperature dehydration and then roomtemperature hydration characteristics of the dehydrated products were studied by thermogravimetric analyses and X-ray diffraction techniques. From isothermal experiments, struvite is found to be

  • Magnesium monophosphate cements derived from

    Magnesium ammonium phosphate hexahydrate [MgNH 4 PO 4 6H 2 O] and Mg (OH) 2 were also detected. Subsequent heating of the cement to 1300°C resulted in the conversion of the three compounds to a single phase of anhydrous magnesium orthophosphate [Mg 3 (PO 4) 2]. The resultant product had a compressive strength of 7000 psi (48.23 MPa) and was thermally stable in air at

  • Magnesium Phosphate Cement - an overview

    Addition of soluble phosphates to Sorel (magnesium oxychloride) cement improves water resistance by the formation of insoluble complexes. This gives rise to aluminium phosphates with a A1 2 O 3 /H 3 PO 4 molecular ratio of 1.1 or 1.4, or to the calcium phosphate hydrates Ca 5 (PO 4) 3 OH or CaH 2 PO 4 H 2 O. The phosphate appears to be adsorbed onto the surface of the hydrating grains, forming ...

    Fundamental properties of magnesium phosphate cement (MPC) were investigated in this paper. The setting time and compressive and bond (i.e., flexural and tensile bond) strengths were measured to assess the applicability, and hydration product was detected by the X-ray diffraction. The specimens were manufactured with magnesia and potassium dihydrogen phosphate
