PZT was studied. The average crystallite size of the PLZT powder was 21nm.Variation of dielectric constant with temperature at 100 kHz frequency was studied. Dielectric constant (e) of PLZT (10/52/48) pellet at Curie temperature (~288⁰c) was found to be 10437. The ferroelectric hysteresis (P-E) loop of PLZT ceramic was studied as a function of applied electric voltage. Study of variation of piezoelectric coefficient (d33) of PLZT pellet with varying polling field shows maximum d33 value… Expand

TLDR
This research confirms that all ceramic compositions have a set of parameters suitable for applications in micromechatronics, for example, as actuators, piezoelectric transducers, and precision microswitches. Expand

TLDR
This text does not treat X-ray diffraction and crystallography in a general way, and would have been better if it were given a more specific title, such as X-Ray Powder Diffraction for Metallurgical Characterization. Expand
