Abstract
Proceeding from the phase diagram of the CaF2–SrF2 system, the stability of crystal–melt interface of solid solution against constitutional supercooling has been calculated. When comparing the stability function F(x) calculated curve with the results of single crystals growing by the Bridgman method, the interdiffusion coefficient of cations in melt was estimated to be D > 2.4 × 10–4 cm2/s.
