The circumstances in which the stability of steady-state regimes of homogeneous crystallization from supersaturated solutions is disrupted and the characteristics of self-oscillations of supersaturation taking place in this process have been determined by analyzing the material balance equation for the dissolved substance and the kinetic equation for the function of sizewise distribution of the crystallized particles. The theoretical and experimental data have been compared. It has been shown that modulation of a number of parameters is a factor responsible for increased stability of steady-state crystallization processes.
