Preparation & pyroelectric properties evaluation of lead lanthanum zirconate
itanate (PLZT) for waste heat power generation

T
he combination of novel electrothermodynamic cycle
based on temporal temperature variations and the
pyroelectric effect is one of the potential method for
utilizing the waste heat energy as a renewable energy
source.
Lanthanum-modified lead zirconate titanate (PLZT)
ceramics with concentration of La (5-7%), are located at
and near the phase boundary between the rhombohedral
and tetragonal ferroelectric phases at room temperature,
which shows that these ceramics are possible as the
candidates for a further improvement of power generating
performance. In this study, we propose the relaxor
ferroelectric ceramic x-mol% La- modified Lead Zirconate
Titanate, PLZT x/65/35 (x= 6, 7, 7.5) which is known for
having a good squareness of hysteresis loop and high
dielectric constant. The power generating potential is
evaluated theoretically by using hysteresis loop and
measurement, and experimentally by using the DSW
circuit to convert waste heat to practical energy.
