Abstract

Lead titanate fibres for use in piezoceramic-polymer composites have been prepared by extrusion of polymeric gels. The gels are formed from solutions of lead acetate, titanium isopropoxide and 2-methoxyethanol. The concentration of the solution, and amount of water and acid added, proved to have a strong influence on the suitability of the gel for extrusion purposes. The drying and firing conditions have been altered to obtain dense, fully crystalline PbTiO3 fibres of 100 μm diameter.
