Abstract

In contrast to known segregation theories (e.g., the Burton-Primm-Schlicter analysis or the adsorption Hall equation), it is shown in the article that segregation can occur under the action of an external force, which causes solution motion through the phase transition region. The external force changes the velocities of component motion. Outside the diffusion layer, the partial velocities of components become different, and, due to the condition of momentum conservation, the concentration of components in the phases changes.
