ABSTRACT:
A voltage-dependent nonlinear resistor from a sintered composition of zinc oxide (ZnO) as a chief component and the following auxiliary components: a rare earth element; cobalt (Co); at least one of magnesium (Mg) and calcium (Ca); at least one of potassium (K), cesium (Cs) and rubidium (Rb); chromium (Cr); boron (B); at least one of aluminum (Al), gallium (Ga) and indium (In); and at least one of antimony (Sb), niobium (Nb), tungsten (W), tantalum (Ta) and phosphorus (P). A voltage-dependent nonlinear resistor from a sintered composition of zinc oxide (ZnO) as a chief component and the following auxiliary components: praseodymium (Pr); cobalt (Co); potassium (K); chromium (Cr); and at least one of antimony (Sb), niobium (Nb) and tungsten (W).
