CaCu3Ti4O12 –silicone resin (CCTO-silicone resin) composites with various CCTO volume fractions up to 0.9 were prepared. Relatively high dielectric constant (ε=151) and low loss (tan δ=0.35) of the composites with CCTO volume fraction at 0.9 were observed. Various theoretical models were employed to predict the dielectric constant of these composites, the dielectric constant obtained via Maxwell-Garnett model were in close agreement with the experimental data. Dielectric measurements were performed from 10Hz to 106Hz and 30 to 2000C. Dielectric constant of CCTO-silicone resin composites showed weak temperature dependence at the measuring temperature range. The results show that the CCTO-silicone resin composites prepared in this study could find some practical applications in the electronic industry.
