The influence of MnO2, PbO, and a mixture of MnO2, PbO, and B^sub 2^O3 on the electrical and dielectric properties of ZnO-V^sub 2^O^sub 5^ ceramics was studied by alternating-current (AC) impedance and variable-temperature dielectric spectroscopy. The results show that, compared with the resistivity...
