Abstract The elastic and thermoelastic constants of cubic LiBaF 3 are measured by ultrasonic methods. As a consequence of the larger packing density which results from the higher coordination number of the Ba ions in LiBaF 3 the values for the mean elastic stiffness and for the refractive index exceed those of LiF and BaF 2 . A quantitative explanation of these properties is given. The values of many other properties range between those of LiF and BaF 2 .
