摘要：

The influence of the formation of eutectic liquid phases during sintering of the ternary varistor system ZnO-Pr6O11-Co3O4 was studied. The temperature at which the samples were observed to be liquid-phase sintered was found to depend on the nominal batch composition. The appearance of the liquid phase had a significant effect on the final microstructure as well as on the electrical properties of the varistors. Small additions of ZrO2, purposely added or resulting from ball-mill contamination, were found to affect moderately the properties of the liquid phases observed in this system.
