The nearly congruent transport of a solid solution by incongruent solid‐vapour and vapour‐solid phase transitions in a closed, almost isothermal system is considered–in particular referring to the crystal growth of pseudobinary A IV B VI solid solutions. The fact is interpreted that the small temperature difference required for the creation of the mass driving force of the process causes composition variations smaller than often assumed.
