Abstract
This paper presents a study aimed at determining the weight ratio of oxide additives for obtaining high-voltage ceramics in the ZnO–Bi2O3–Sb2O3–Al2O3–Co3O4 system containing 90 wt % ZnO, with a leakage current density under 1 μA/cm2. The ceramic containing the oxide additives in the ratio Bi2O3 : Sb2O3 : Al2O3 : Co3O4 = 0.25 : 0.17 : 1.4 : 1.4 has a nonlinearity coefficient as high as α = 69, a leakage current density as low as Il = 0.4 μA/cm2, and a breakdown voltage Vb = 4.1 kV/mm.
