abstract	Lead zirconate titanate (PZT) fibers have been prepared via sol-gel route using acetic acid to acidify the precursors. The molecular structure of precursors is investigated by FTIR, liquid and solid C-13-NMR. The crystallization behavior and the microstructure of PZT fibers are analyzed and discussed. The dielectric properties are also measured by piezoAFM. A pure perovskite phase was obtained after heat treatment at 973 K. The domain structure was observed, which showed that PZT fibers have ferroelectric properties. The permittivity of the PZT fiber was 544. (C) 2004 Elsevier Ltd and Techna Group S.r.l.
