The dependence of loss tangent (tanδ) and both real and imaginary parts of the dielectric constant (ɛ′ and ɛ″) on temperature in the range 298–923K and frequency in the range 10 3 –10 6 Hz for flux grown CdTiO 3 single crystals is reported. The lnσ ac versus T plots suggest the conduction mechanism to be ionic hopping conduction. From lnσ ac versus frequency curves, it can be seen that the slope decreases with the rise in temperature, suggesting that the ionic hopping conduction diminishes with the rise in temperature. The activation energy at various fixed frequencies is calculated from the slope of the graph between lnσ ac versus 1/T (×10 3 K −1 ). Thermal behaviour of flux grown CdTiO 3 crystals using thermoanalytical techniques including TG, DTA and DTG is discussed. Thermal analysis suggests decomposition of CdTiO 3 in the temperature interval of 1386–1693K leading to the formation of TiO 2 as the final product. Results obtained on application of TG based models viz. Horowitz–Metzger, Coats–Redfern and Piloyan–Novikova are reported. The results of kinetics of thermal decomposition suggest contracting cylinder model as the one that is relevant to the decomposition of CdTiO 3 . The kinetic parameters viz. the order of reaction, activation energy, frequency factor, and entropy of activation using the above mentioned models are computed.
