Monoclinic ZrO2 fiber/PZT composites were fabricated by slip casting and pressureless sintering. The isoelectric points of ZrO2 and PZT were 4.8 and 7.6, respectively. Homogeneous composites were obtained by adjusting pH of slurries at 10. Although densification was inhibited by addition of fibers, a composite with 20vol% ZrO2 fibers attained a relatively high bulk density of 93%. The grain size of PZT matrix was almost invariant with addition of fibers. EDS (Energy Dispersion X-Ray Spectroscopy) and XRD (X-Ray Diffractometer) analyses verified that no macroscopic reaction between ZrO2 fibers and PZT occurred.
