Abstract

Pure and Pbo-B2O3 -doped glass to CCTO (CaCu3Ti4O12) ceramics were prepared by a conventional solid-state reaction method, and the effects of glass doping on the microstructures and electrical properties of these ceramics were investigated. CCTO has challenged for the last few years the scientific community due to its large dielectric constant, which is almost temperature and frequency independent. This makes the material desirable for many electronic applications. However, the dissipation factor is very large, with tan 6 values, at room temperature and 1 kHz, higher than 0.1. In our work we report how the addition of glass lowers the dielectric loss and, high dielectric constant values are still can be reached. The sample of doped CCTO with 0.05 of by weight, presents, at room temperature, a large dielectric constant, over 360000, and a dissipation factor around 0.09, which represents a decrease on tan 6 relatively to the CCTO undoped sample.
