Title: Dielectric properties of CaCuTiO prepared by sol-gel self combustion technique.
Authors: Kumar, C.
Abstract: The preparation of Calcium copper titanate (CCTO) nanopowder was carried out by a sol-gel self combustion method. The X-ray diffraction analysis indicated that the samples calcined at 800 °C were fully crystallized in the CCTO phase. The results of atomic force microscope showed the particles size of CCTO was in the range of 60-80 nm. The absorption bands corresponding to vibrations of Cu-O, Ti-O-Ti and νCa-O were observed at 512, 450 and 562 cm using FTIR. The samples sintered at 950 °C showed the densities as high as 97% of theoretical density. The grain sizes of sintered pellets were determined by HRSEM. The dielectric properties of prepared samples were studied by LCR meter.
