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.
