Abstract
Solid state synthesis route was employed to form Ba0.85Ca0.15Zr0.1Ti0.9O3 powder. The calcined powder was high energy ball milled at different milling speeds to get powders of different particle sizes. XRD pattern of the ceramics made from these powders show the presence of pure perovskite. This paper deals with a systematic study of the pyroelectric and the fatigue properties of the ceramics. The room temperature pyroelectric coefficient (p) attains the minimum value p = 0.119X10−8 C cm−2 K−1 for the ceramic made from the powder milled at 250 rpm. The fatigue was also found to be minimum for the same ceramic samples.
