Morphological stability of the solid‒liquid interface during melt crystallization of Pb1–xCdxF2 solid solution

Abstract

The stability function of the solid‒liquid interface for PbF₂–CdF₂ solid solution with respect to constitutional supercooling is calculated using the phase diagram of the system. The calculated curve is typical of the systems with continuous solid solutions, having minima points in the liquidus and solidus curves. This dependence can be used to estimate the technological parameters of the process which are required for growing crystals with the high optical quality.
