摘要

The electrical properties of purl and Li2O-doped CuO/Fe2O3 solids were investigated. Pure and Variously doped solids were subjected to thermal treatment at 1073-1273 K and the amount of dopant was varied between 0.84 to 3.36 mol%. The effect of precalcination temperature and amount of Li2O added on the electrical conductivity sigma, activation energy E-a and dielectric constant epsilon* were studied. The Variation of epsilon ' and epsilon " as a function of frequency for pure and variously doped solids precalcined at different temperatures was also investigated. The results obtained were discussed. (C) 2001 Elsevier Science B.V. All rights reserved. [References: 23]
