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.
