Abstract

Homogeneous and stoichiometric PbTiO₃ and PbZr_o.52Ti_o.48O₃ gel fibers were drawn from viscous solutions prepared by sol-gel processing of alkoxide precursors. The fibrous gels on heating at 450 and 600 °C, respectively, formed the well-crystallized phases of PbTiO₃ and PbZr_o.52Ti_o.48O₃ Fibers heat treated at 700 °C are a few centimeters long and 50 to 150 μm in diameter. PbZr_o.52Ti_o.48O₃ fibers subjected to heat treatment at 700 °C for 1 h consisted of fully dense submicron grains (0.15 to 0.2 (μm). However, PbTiO₃ fibers under analogous conditions showed a few micropores with grains of ~0.1 μm. Dielectric constants of these PbTiO₃ and PbZr_o.52Ti_o.48O₃ fibers were approximately 300 and 800, respectively.
