In this study, the CaCu 3 Ti 4 O 12 (CCTO) ceramic phase was synthesized by microwave heating in a much shorter time compared to the conventional heating methods. The results indicate that microwave processing is a promising method for preparing CCTO ceramics. CCTO was prepared using a domestic micr

## 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

Bi 4-x La x Ti 3 O 12 (BLT) ceramics were prepared and studied in this work in terms of La 3+ -modified microstructure and phase development as well as electrical response. According to the results processed from X-ray diffraction and electrical measurements, the solubility limit (x L ) of La 3+ int
