dc.description.abstractBy using lead acetate, zinc propionate, niobium ethoxide, zirconium propoxide and titanium butoxide as precursors, zinc and niobium modified lead zirconate titanate (PZN-PZT) gel fibers were fabricated by the sol-gel method. Prolyzed and sintered, The PZN-PZT ceramic fibers with a diameter of about 25 μm were obtained. The SEM micrographs show that these ceramic fibers are dense and uniform. The X-ray diffraction patterns show that sintering temperatures will affect the crystal structure of PZN-PZT ceramics. When the sintering temperature is higher than 1250°C, the sintered ceramics and ceramic fibers have a pure perovskite structure. The densities of the bulk ceramic and ceramic fiber are 7.70 × 103 kg/m3 and 7.80 × 103 kg/m3, which were measured by Archimedes method. The electromechanical coupling coefficient kt , piezoelectric coefficient d33 and relative permittivity e of the PZN-PZT fiber/epoxy 1-3 composite disk with 63% fibers loaded are 0.65, 403 pC/N and 1300 respectively. The kt, d33 and ε of the PZN-PZT ceramics made from the sol-gel powder are 0.48, 600 pC/N and 2627 respectively.en_US
