The technique of the analytical electron microscopy was used for a study of changes in chemical composition, which occur at grain boundaries of ZrO2-3% mol Y2O3 ceramics sintered at 1775 K for different periods of time. Two phenomena were detected. First one shows similarity to the diffusion induced grain boundary migration. The second one is associated with the formation of transition zone between two grains containing different amount of yttria.
