Аннотация: The Pb8La2(GeO4)(4)(VO4)(2) and Pb8Nd2(GeO4)(4)(VO4)(2) germanatovanadates with the apatite structure have been prepared by solid-state reactions, by sequentially firing stoichiometric mixtures of PbO, La2O3 (Nd2O3), GeO2, and V2O5 in air at temperatures of 773, 873, 973, and 1073 K. The effect of temperature on the heat capacity oПоказать полностьюf the resultant polycrystalline samples has been studied by differential scanning calorimetry at temperatures from 350 to 950 K using polycrystalline samples. The experimental C (p) (T) data have been used to evaluate the thermodynamic functions of the lead lanthanum and lead neodymium germanatovanadates.
