K5Ca0,5Hf1,5(MoO4)6: THERMAL DEFORMATIONS AND IONIC CONDUCTIVITY
Compound K5Ca0,5Hf1,5(MoO4)6 was obtained using ceramic technology. The present study found that the compound melts incongruently at temperature of 651°C. Its crystal structure was specified by the Rietveld method. It showed that the conductivity of K5Ca0,5Hf1,5(MoO4)6 at 500 °C reached values of 5,11∙10–4 S/cm, which exceeds the conductivity of similar potassium ternary molybdates studied previously. Thermal deformations were studied by high-temperature powder X-ray diffraction in the temperature range of 30–500 °C. Ternary molybdate K5Ca0,5Hf1,5(MoO4)6 belongs to materials with high anisotropic thermal expansion (αV ~ 47×10–6 °C–1).
