Abstract

Materials explaining the mechanism of spatial differentiation of solution composition with the participation of the gas phase and its role in the creation of non-equilibrium conditions that ensure recrystallization of solid products are presented. Calculations of equilibrium in a number of systems of alumina production are presented. Indicators of non-equilibrium of solutions and their dependence on the leading technological parameters of the process are established.
