Abstract
Bulk ferro/piezoelectric ceramics are the backbone for several components utilized in
communication systems, industrial automation, medical diagnostics, information-technology,
energy storage and harvesting. From the application point of view, ferro/piezoelectric materials
should have high piezoelectric coefficients, high remnant polarization (Pr), low coercive field
(EC), wide temperature stability and good mechanical strength [1]. In most of the high
performance piezoelectric applications, the material of choice is ultimately based upon lead
based materials such as PZT (i.e., Pb(Zr, Ti)O3). Even though PZT has excellent piezoelectric
properties suitable for device applications, the prime concern is about lead (Pb) which is highly
toxic and hazardous in nature. Hence, it has become a serious threat for environmental protection
during the waste disposal and also it indirectly induces health related issues. In this regard,
worldwide environmental considerations are demanding the elimination of lead-based materials
from all consumer items [2].
