    • Abstract

       

      The lattice parameters of CdF2 andβ-PbF2 have been determined over the temperature range 300–670 K. The coefficient of expansion at room temperature is 21·3 × 10−6 K−1 and 25·4 × 10−6 K−1 for CdF2 and PbF2 respectively and it increases linearly with temperature over the range of temperature covered. The Grüneisen parameter decreases with temperature in both the crystals.
