Accelerated mass transfer involving the liquid phase in solids

The results of theoretical and experimental research on accelerated mass transfer involving the liquid phase in solids are analyzed. The kinetic regularities of mass transfer, the thermodynamics of grain-boundary wetting and the mechanisms of formation of liquid-channel grain boundary structure in polycrystalline materials are considered. The possibility of design of new membrane materials based on solid oxide–oxide melt composites and possessing high mixed ionic-electronic conductivity is demonstrated. The bibliography includes 224 references.
