Senapati, Amlan Swetapadma (2011) Characterizations of Sol gel Synthesized (1-x)BZT-xBCT Ceramics. MSc thesis.



Barium zirconate titanate – Barium calcium titanate [(1-x)BZT-xBCT] (48BZT-52BCT, 50BZT-50BCT, 52BZT-48BCT) ceramic were prepared by sol-gel method. The sample was calcined at 1100°C. The X-Ray diffraction of calcined powder showed the formation of single pervoskite phase with no impurity peaks. 48BZT-52BCT, 50BZT-50BCT and 52BZT-48BCT were sintered at two temperatures i.e., 1200°C and 1300°C. The SEM images of the sintered pellets showed that the grain size varied from 800nm to 2μm. The dielectric property was studied under the frequency range from 100 Hz to 1 MHz and also by varying the temperature from 30°C to 200°C. The PE Loop of the sample was obtained by PE Loop tracer which confirmed the ferroelectric effect in 48BZT-52BCT, 50BZT–50BCT, 52BZT-48BCT ceramics.
