Abstract

The binary phase diagram CaF $_2$ --SrF $_2$ was investigated by differential thermal analysis (DTA). Both substances exhibit unlimited mutual solubility with an azeotropic point showing a minimum melting temperature of T_\mathrm{min}=1373^{\circ} $C for the composition Ca$ _{0.582} $Sr$ _{0.418} $F$ _2$. Close to this composition, homogeneous single crystals up to 30 mm diameter without remarkable segregation could be grown by the Czochralski method.
