Abstract  

Excess CaO type non-stoichiometric calcium zirconate was prepared by a co-precipitation method, and the impedance properties was investigated by AC impedance determination. The results show that precursor powder can be synthesized into pure orthorhombic CaZrO3, the total electrical conductivity significantly increases with temperature increases, and the activation energy was calculated to be 1.17eV. Both relaxation time and capacitance decrease dramatically with the rising of temperature. The permittivity of grain boundary was found higher than that of grain at low temperature. In this way, the heterogeneous distribution of oxygen vacancies was indicated, and the doping mechanism of CaO in Ca1−xZrO3−δ matrix was deduced to be heterogeneous. However, permittivity decreases evidently with temperature rises, which
suggests the oxygen vacancies distribute more homogeneously at higher temperature.

Key words:  inorganic non-metallic materials      calcium zirconate      AC impedance      permittivity      oxygen vacancy
