Synthesis and Thermodynamic Properties of Germanate Tb2Ge2O7
Germanate Tb 2 Ge 2 O 7 has been prepared by solid-phase synthesis from a stoichiometric mixture of Tb 2 O 3 and GeO 2 by sequential firing in air at temperatures of 1273–1473 K. The effect of temperature on its molar heat capacity has been studied by differential scanning calorimetry. According to...
