## Abstract The solid‐state procedure is used to produce bulk ceramics of CCTO (CaCu~3~Ti~4~O~12~). The samples of the CCTO ceramic are studied by X‐ray powder diffraction and infrared and Raman scattering spectroscopy. The infrared and Raman scattering spectroscopy confirm the formation of the CCT

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
## Abstract CaCu~3~Ti~4~O~12~–polyethersulfone (CCTO–PES) composites with various CCTO volume fractions up to 0.5 were prepared. Relatively high dielectric constant (__ε__ = 32.7) and low loss (tan __δ__ = 0.063) of the composites with CCTO volume fraction at 0.5 were observed. Various theoretical
