Abstract
The influence of double sintering temperature on the phase structure, micro-structure and piezoelectric properties of Ba1-xCaxZr0.1Ti0.9O3 (x = 0.055) double sintered ceramics has been systematically studied. The pellet sample preparation and characterization have been reported in this paper. The converse piezoelectric properties of the Ba1-xCaxZr0.1Ti0.9O3 (x = 0.055) were observed. Depending upon the sintering temperature, the grain size and density of BCZT ceramics have been changed. The P-E loops, strain%, and the polarization current were measured. The value of d33 was decreasing with the application of an electric field in case of double sintered pellets. For sample x = 0.055, the value of d33* at 1300, 1400 and 1450 °C temperature, was 173 (pm/V), 130 (pm/V), and 75 (pm/V), respectively, at applied field 29.33 kV/cm.
