Abstract: In the current study, Bi2/3Cu3Ti4O12 (BCTO) ceramics were prepared by mechanical
ball mill of the elemental oxides followed by conventional sintering of the powder without any
pre-sintering heat treatments. The sintering temperature was in the range 950–990 C, which is
100–150 C lower than the previous conventional sintering studies on BCTO ceramics. All the ceramic
samples showed body-centered cubic phase and grain size 2–6 m. Sintering temperature in the
range 950–975 C resulted in comparatively lower dielectric loss and lower thermal coefficient of
permittivity in the temperature range from 􀀀50 to 120 C. All the BCTO ceramics showed reasonably
high relative permittivity. The behavior of BCTO ceramics was correlated with the change in
oxygen content in the samples with sintering temperature. This interpretation was supported by the
measurements of the energy dispersive x-ray spectroscopy (EDS) elemental analysis and activation
energy for conduction and for relaxation in the ceramics.
