Аннотация: The Pb10-xGdx(GeO4)(2-x)(VO4)(4-x) (x = 0.5, 1.0) apatites were synthesized by the solid-phase synthesis by roasting stoichiometric mixtures of PbO, Gd2O3, GeO2, and V2O5 in air at temperatures of 773-1073 K. Their crystal structure was determined using X-ray diffraction analysis. The high-temperature heat capacity (350-1000 K) wasПоказать полностьюmeasured by differential scanning calorimetry. The experimental data Cp = f (T) were used to calculate the thermodynamic properties of apatites.
