Viter V. Synthesis and properties of solid solutions of substitution on the base of hydrated phosphates of bivalent 3-d metals and Mg

The dissertation is devoted to synthesis and investigations of new solid solutions of substitution on the base of hydrated phosphates of bivalent 3-d metals and Mg. The new solid solutions on the base of CuHPO4·H2O, Cu3(PO4)2·H2O, Cu2(OH)PO4·xH2O, Zn3(PO4)2·4H2O, а-Zn3(PO4)2, MgHPO4·3H2O and MnHPO4·3H2O have been synthesized. The formation of solid solutions with superstructure (concerning structures of CuHPO4·H2O and Cu3(PO4)2·H2O) has been shown. Ni(H2PO4)2·2H2O and solid solutions M1-XNiX(H2PO4)2·2H2O, where M - Co, Zn, Mn, Mg have been obtained. The unit sell is monoclinic, sp. gr. Р21/n. Ni(H2PO4)·2H2O has structure of "M(H2PO4)·2H2O-type" (M - Co, Zn, Mg, Mn, Fe, Cd). The solid solutions between hydrated phosphates of Co and Ni with different protonization level have been synthesized. The homogeneity ranges, unit sell constants have been determined for obtained solid solutions. IR spectra, thermolysis have been investigated.
