Isothermal and non-isothermal transformations of polycrystalline NH4M(II)PO4 . H2O (where M(II) is Mg, Mn, Co, Cu) in atmospheres of various gases (open air, humid air, H2O vapour, P(H2O) = 20 hPa, gaseous NH3, P(NH3) = 5-925 hPa, vacuum, p = 10(-5) hPa) were studied by DTA, TG, DTG, XRD, PC, and chemical analyses at 20-950-degrees-C. The kinetic characteristics of the evolution of gaseous products and of the essential processes of dehydration and deammoniation, and the anionic rearrangements are considered.
