The degradation mechanism of ZnO-based ceramic varistors was investigated by electrochemical hydrogen charging, in which ZnO ceramics were placed in 0.01 M NaOH solution to evolve hydrogen on them by electrolysis of water. After the treatment, the conductivity of the ZnO ceramics was greatly increased and the temperature dependence of resistivity changed from negative temperature coefficient (NTC) type to metallic type. X-ray diffraction analysis showed that ZnO was reduced to Zn at ambient temperature. It was proposed that the reduction of ZnO-based grains by atomic hydrogen at ambient temperature causes the degradation of ZnO-based ceramic varistors.
