Abstract

The densification behavior a PZT-based composition with additions of BiFeO₃ as a flux was studied. Two different PZT powders were studied with varying initial particle sizes. Results clearly showed that BiFeO₃ forms a low temperature liquid that aids in the densification behavior, with 3 mole% being optimum. Fine particle sizes substantially improved the density at low temperatures, with the net result that ceramics could be densified in air without the aid of a lead source. The corresponding electromechanical properties were typical of a hard PZT formulation
