摘要

PZT nano piezoelectric fibers were prepared by hydrothermal-template method using activated carbon as template. The optimal hydrothermal conditions for preparing PZT nano fibers were investigated, such as pH value, reaction temperature and time. Based on the observation from scanning electron microscopy (SEM) show that the diameter of PZT fibers is around 100 nm with the length up to a few microns, and the fibers are arranged orderly in one direction very well. Novel PZT ceramic made of the fibers was obtained through pressing carefully the fibers along a direction as possible, then sintering at the temperature of 1050 ℃ for 1.5 hour. The piezoelectric properties were determined by impedance analyzer, precision LRC meter and quasistatic measuring instrument. The results indicated that the novel PZT ceramic made of nano-fibers has high piezoelectric constant, while its dielectric losses is very low. The PZT textured creamic had a high value of Kt/Kp (1.8567) compared with the conventional PZT ceramic made of milled PZT powder. It means that the PZT ceramic shows very good anisotropic property and has potential application as a sensor or device with high direction sensitivity.
