Sample preparation and varistor physical properties measurement of ZnO+0.01Sb2O3
The disc-shape ZnO+0.01Sb2O3 samples were prepared by standard ceramic techniques. The sample indicates white colour and was characterized by XRD. The prepared sample is varistor which shows breakdown field strength of 87.18 V/mm and non-linearity exponent (α) of 38.179. It is worth noting that the...

| Summary: | The disc-shape ZnO+0.01Sb2O3 samples were prepared by standard ceramic techniques. The sample indicates white colour and was characterized by XRD. The prepared sample is varistor which shows breakdown field strength of 87.18 V/mm and non-linearity exponent (α) of 38.179. It is worth noting that the high electric field strength of 5128.2 V/mm causes sample resistance changing. Sample resistance before and after poling were 189.13 kΩ and 6.516 kΩ, respectively. |
