| Abstract: | Under different condition of applied voltage, the resistivity of fine grain BaTiO3 ceramics was measured. Combined the frequency resonate of complex impedance, the influences of grain and grain boundary on resistivity of ceramics were analyzed based on a simple equivalent circuit, complex dielectric mode and the theory of polarization electrical current. The analytical results are according with that of exoeriments. |
