Abstract

• Calcium copper titanate ceramics were synthesized by solid-state reaction method. The structural and microstructural properties of sample powder were examined by X-ray diffraction (XRD) and scanning electron microscope (SEM). The capacitance, resistance and dissipated factor of ceramics were measured at frequency range 1 kHz to 25 kHz by LCR meter. The average dielectric constant, of ceramics ( at 850˚C for 5h different heat treatment four times) were found to be 94.4,99.4,112.7 and 133.7 in the frequency range from 1kHz to 25kHz. The values of the dielectric loss and conductivity of samples were calculated.
