In this paper, the equivalent intergranular impedance model of BaTiO/sub 3/-ceramics is generated taking into consideration two types of connections between grains. The models are applied to a cluster of up to three spherical and polyhedral grains contacting each other. The relations between the most dominant electrical parameters (capacitance and conductance) of the intergranular microcondenser and geometric parameters are established. © 1999 IEEE.
