In this work, single-phase cubic perovskite CaCu 3 Ti 4 O 12 powders have been synthesized successfully by microwave heating with a relatively low energy consumption and short time, compared with conventional synthesis. The reaction evolution of forming CCTO has been suggested according to the XRD d

In the present work we demonstrate that in addition to the well-known colossal-dielectric-constant material CaCu 3 Ti 4 O 12 various members of the series Ln 2/3 Cu 3 Ti 4 O 12 with Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er and Tm also exhibit giant values of the dielectric constant. Just as C
