Abstract: ZnO-based varistor ceramics doped with fixed La2O3 and different Y2O3 have been fabricated by the conventional solid-state reaction route. Phase composition, microstructure, and electrical properties were studied by X-ray diffractometry (XRD), scanning electron microscopy (SEM),… read more here.
