In this study, the effect of as-prepared annatase TiO<sub>2</sub> nanotubes on the sintering behavior and the piezoelectric properties of lead zirconate titanate (PZT) ceramics was investigated. Two types of PZT (with the use of TiO<sub>2</sub> nanotubes and commercial TiO<sub>2</sub>) were prepared by a conventional oxide-mixing method. The density of samples using TiO<sub>2</sub> nanotubes tended to increase and the sintering temperature of these ceramics decreased. The electromechanical coupling factor (k<sub>p</sub>) of PZT ceramics was improved significantly by the use of TiO<sub>2</sub> nanotubes.
