An extensive study is made of thermophysical and anharmonic properties of fluorite compounds using an interionic potential, which consists of a long‐range Coulomb and three‐body interactions and the short‐range overlap repulsion and van der Waals attraction. The agreement achieved between experimental and the theoretical results on third‐order elastic constants and pressure derivatives of second order elastic constants are generally better than those obtained by others. This potential succeeds in predicting various thermophysical properties, like compressibility and its pressure and temperature derivatives, thermal expansion and Grüneisen parameters of seven crystals of fluorite structure.

## Abstract The effects of three‐body forces on the thermophysical and anharmonic properties of rare gas solid (RGS) mixtures are investigated using the virtual crystal approximation and an interatomic potential consisting of the long‐range van der Waals dipole–dipole interaction and three‐body for
