Abstract

LEAD ZIRCONATE TITANATE (PZT), with the general composition of Pb (ZrxTi1-x) O3, 0<x<1, is a well-known ferroelectric and piezoelectric ceramic material with high spontaneous polarization, dielectric permittivity, and piezoelectric coefficients peaking at compositions near the morphotropic phase boundary or MPB (x=0.52). In the current research, porous anodic alumina (AA) membranes were used for the preparation of the deposition template in order to provide a mold. The alumina membranes were fabricated through two-step anodizing of the aluminum foils in a cooled anodizing cell at 1ºC, using phosphoric acid (10 wt.%) as the electrolyte. Stabilized PZT sol, with the composition of Pb1.1 (Zr0.52Ti0.48) O3, was prepared through the chemical modification of the organo-metallic precursors of zirconium, and titanium with glacial acetic acid. The precursor solution was then driven into the template channels under the influence of a DC electric field. The filled mold were dried at 100oC, and subsequently annealed at 700oC to develop the desired perovskite structure. Scanning and transmission electron microscopy (SEM and TEM) investigations showed that PZT NANOTUBEs have efficiently grown in template channels. Energy dispersive X-ray (EDX) investigations confirmed the composition of the grown NANOTUBEs. X-ray diffraction (XRD) investigations indicated that the PZT NANOTUBEs possess mainly the desired perovskite phase. The electron diffraction patterns also demonstrated the polycrystalline nature of the grown NANOTUBEs.
