The modeling of distribution of mobile charge carriers in the space-charge regions at grain boundaries of ceramic materials was done. The standard free chemical potentials of the defects were set to be constant in accordance with the space-charge model. The modeling predicted that a contact of two grains that differed only in size, led to a redistribution of mobile ions between grains.
