Abstract

The materials of the pilot study, which establishes the dependence of the kinetics of mass crystallization of aluminum hydroxide on the extent of metastable alkaline aluminate solutions. Shown that changes in the level of metastability of the environment of crystallization is the lag in time from changes in state parameters of physico-chemical system. The theoretical a justification of the transition from one level of the metastable state to another due to time constraints, changing the structure of unstable solutions.
