  • The thermal conductivity, lambda , and heat capacity per unit volume, rho cp, have been measured under hydrostatic pressure up to 1 GPa at room temperature, using a dynamic two-strip method. The standard deviation of lambda and rho cp was always better than 0.2%. The volume dependence of lambda expressed in terms of the Bridgman parameter, -( delta ln (lambda) / delta ln V)T, was found to be 7.9 for LiF and 9.2 for CaF2. The specific heat capacity, cp, calculated from the measured rho cp, was found to decrease slightly with increasing pressure.
