Abstract
The linear thermal expansions of CaF2, BaF2, SrF2, PbF2 and SrCl2 have been measured from room temperature up to their melting points. The linear coefficient alpha exhibits a Schottky-like bump similar to that observed previously for the heat capacity, Cp, and associated with fast-ion conduction in these fluorite-structure materials. Values for the Gruneisen parameter gamma (T) are included.Keywords
