Giant Dielectric Constant Response of the Composites in Ternary SystemCuO-TiO2-CaO. -Giant dielectric constants >10 4 occur for most composites in the CuO-rich region and in the region along the CaO-CuO binary line of the title system. These composites can be fabricated in a single step at a sintering temperature of 950°C. A comparable giant dielectric constant is obtained for composites in the CaCu 3 Ti 4 O 12 -rich region when sintered at 1050°C. The grain size distributions in most composites with giant dielectric constants are bimodal. Smaller grains with secondary phases are located on the surface or the boundaries of the bigger grains, which are composed of the predominant phases. -(VEITH*, M.; REN, S.; WITTMAR, M.; BOLZ, H.; J.
