Research aim - to establish the nature and features of solid-phase hydrolysis of crystallohydrates on the example of solid solutions hydrated mono- and diphosphates bivalent metals. Methods of research and the equipment - differential and thermal (derivatograf G 1500 D), chemical, X-ray phase (Dron-4M, Cu Ka) analyses, methods of a spectroscopy (Specord 75 UR). By spectroscopic and thermoanalytical researches of solid solutions hydrated mono- and diphosphates Mg, Mn(II), Co(II), Zn of various hydration is established sequence of the solid-phase transformations accompanying them termolysis. The nature and features of solid-phase hydrolysis which thus happens is opened. Correlations between depth of its realization, a power condition of water in structure of crystallohydrate, the cation nature, degree of a protonization and hydration of solid solution are established. Optimum conditions of receiving and thermal stability of solid solutions waterless mono - , di- and polyphosphates Mg, Mn (II), Co (II), Zn are defined. Conditions of their directed synthesis are proved. Solid solutions of composition Mn3.xMux(P04), Mn2.xMnxP207 and Mn2.xMnxP40i2 (Mn = Mg, Mn, Co, Zn) are synthesized. Their chemical nature, structural features, the major characteristics is established. Efficiency of using as preparation with fungicide activity for treatment of gratae of oak silkworm, as mineral feed addition for agricultural animals is shown. Scientific and methodical recommendations about purposeful synthesis of waterless solid solutions mono -, di- and polyphosphates of bivalent metals of the set structure and properties are prepared. Use area - the chemical industry, the agro-industrial enterprises, NRI NAN and NAAN of Ukraine.
