Abstract

In this study, the effect of as-prepared annatase TiO₂ 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 TiO₂ nanotubes and commercial TiO₂) were prepared by a conventional oxide-mixing method. The density of samples using TiO₂ nanotubes tended to increase and the sintering temperature of these ceramics decreased. The electromechanical coupling factor (k_p) of PZT ceramics was improved significantly by the use of TiO₂ nanotubes
