Abstract

A fibrous lead titanate (PbTiO3) powder with light-yellow colour has been prepared by hydrothermal synthesis. The influences of Pb/Ti ratio (0.3 to 1.0) in the mixture and reaction time on the formation of fibrous PbTiO3 under hydrothermal conditions have been investigated. The preferable conditions for preparing fibrous perovskite-type PbTiO3 from fibrous potassium titanate are that the Pb/Ti ratio is 1.0, reaction temperature 150 °C and time 72 h. The particles of fibrous powder of perovskite type are usually less than 2 μm in diameter and more than 50 μm in length. The fibrous morphology is essentially unchanged up to about 650 °C, but it disappeared after heating to 1000 °C.
