Abstract: | The thermophysical properties of LiKSO4 crystals were studied around the high-temperature phase, atT c 2=943 K. A Heraeus (DSC) technique was used to measure the specific heat,c p, while the thermal conductivity,K, was measured by the linear heat flow steady-state method. The measured parameters showed an anomaly in the temperature dependence of bothc p andK. Anisotropy in the thermal conductivity coefficient was also observed in the different crystallographic axes. |
