Abstract:
LiScGeO$_4$ and LiScSiO$_4$ compounds were obtained by solid-phase synthesis from Li$_2$CO$_3$, Sc$_2$O$_3$, GeO$_2$ (SiO$_2$). Their crystal structure has been refined using X-ray diffraction. The high-temperature heat capacity (320–1050 K) of the obtained lithium-scandium germanate and silicate was measured by differential scanning calorimetry. The thermodynamic properties were calculated based on the experimental data about heat capacity. Keywords: differential scanning calorimetry, solid-phase synthesis, thermodynamic properties.
