| Abstract |
| Piezoelectric materials are used for various commercial and strategic applications.
For most of the current generation applications the usage temperature is about 150oC
and therefore, ceramics like lead zirconate titanate or lead-free ceramics such as
potassium sodium niobite which exhibit Curie temperature (TC) in between 350o and
450oC are useful. However, in the next-generation applications, the usage temperature
is expected to be more than 500oC. As a thumb rule usage temperature of a ferroelectric
ceramic is 1/2 of TC and hence, ceramics with a TC greater than 1000oC are required
for such applications. Perovskite layer structure (PLS) piezoceramics exhibit TC well
above 1000oC and thus, are the most promising materials for high temperature
piezoelectric applications. With this background, we review the synthesis, fabrication
and structural aspects of the PLS piezoceramics. We also discuss the peculiar
microstructure and dielectric properties of these ceramics along with their advantages
and limitations.
