Sr and Zr Co-Doped CaCuTiO Ceramics with Improved Dielectric Properties.

The dielectric constant of CCTO materials can be as high as 10, which makes it suitable for use in electronic devices but the high dielectric loss limits its application. In this paper, a series of Sr and Zr co-doped CCTO ceramics having the formula CaSrCuTiZrO ( = 0.1, 0.
