Abstract

Measurements of thermal conductivity, λ, for the alkaline earth compounds SrCl2 and SrF2 indicate that the λ of SrC12 is less than that of SrF2 by a factor of 4 to 5 over the temperature range from 85 to 400 K. This difference can be related to the differences in other parameters of the two compounds. At the lower end of the temperature range, the thermal resistivities, λ−1, of both materials are linear; but large positive deviations occur at the higher end of the range. Calculated values using an equation for acoustic phonon conduction agree with the experimental values to within 30% over the entire measurement range. The positive deviations from linearity appear to be due to the effect of lattice dilation on the Debye temperatures and Grüneisen constants.
