This work reports on homogeneous varistor ceramics prepared from a mixture of impurity‐doped zinc oxide (C) [E. Suzuki et al., IEEE Trans. Electron Dev. 47, 354 (2000); F.L. Souza et al., Mater. Chem. Phys. 80, 512 (2003)] and nonpolar polyethylene (PE) using a hot pressing method. The content of the composite components was varied from 10% (90%) to 70% (30%) of C (PE) and the thickness of the samples obtained was 40 or 150 μm. The voltage–current characteristics and electroconductivity with applied voltage were measured for all the samples obtained at room temperature. Also, the same samples were tested using infrared absorption and X‐ray diffraction methods. As a result of these studies, the influence of ceramic composition on the ceramic parameters was established. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
