Abstract :
Lead zirconate titanate (PZT) powder with fibroid morphology was prepared via hydrothermal synthesis and heat treatment using organic mineralizer, tetramethylammonium hydroxide pentahydrate (TMAH). The structure and morphology of the resultant fibers were investigated by X-ray diffraction (XRD) analysis and transmission electron microscope (TEM) observation, The TMAH concentration, hydrothermal reaction time, calcining temperature, calcining time both had effects on the microstructure and morphology of the fibrous PZT. The result was analyzed and discussed to confirm the parameters of hydrothermal synthesis technics. Besides, the changes of dielectric constant and dielectric loss with frequencies were investigated in detail. Fibrous PZT powders was pressed into slice, calcined, coated with electrode and polarized. The piezoelectricity capability detection results indicated that piezoelectricity constant increased linearly along with electric voltage
