Abstract
Ultrafine powders of (Pb0.93La0.07)(Zr0.60Ti0.40)O3 (hereafter designated as PLZT) have been synthesized from oxide powders using a highenergy ball milling technique in air atmosphere. The powders milled in tungsten carbidevials using tungsten carbide balls were all about 30 nm in size. XRD revealed the formationof a significant amount of the perovskite PLZT phase at room temperature itself. TG-DTAand DSC studies were used to analyze the thermal properties of the nanopowders, in orderto understand the reaction kinetics. The bulk ceramic samples were subjected toelectrical poling, prior to performing resonance measurements on them, in order todetermine the piezoelectric and electromechanical coupling coefficients. Poled samplesexhibited large strains under the influence of applied electric fields, with limitedhysteresis. In order to evaluate the reliability of the material for possible use assensors and actuators, sintered specimens were subjected to mechanical propertyevaluation.
