Phase diagram analysis and crystal growth of solid solutions Ca_{1-x}Sr_xF_2
The binary phase diagram CaF--SrF 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}_{0.582}_{0.418}_2$. Close to this composition, homogeneous single
crystals up to 30 mm diameter without remarkable segregation could be grown by
the Czochralski method.Comment: accepted for publication in J. Crystal Growt
