Mass crystallization of ellipsoidal particles from solutions under conditions of kinetically controlled crystal growth

Mass crystallization was described in terms of a crystal size distribution function (CSDF). Particles in the form of ellipsoids of revolution were con sidered. Needle-shaped and flattened (round) crystalline particles were con sidered limiting cases. The problem was reduced to the solution of a system of ordinary differential equations for the CSDF moments. The stationary so lution to the system was investigated for stability, and criteria of stabil ity were derived. It was shown that when stability is violated, oscillation s arise in the system. The characteristics of the oscillation regime were i llustrated by examples.
