摘要

Lead lanthanum zirconate titanate (PLZT7/60/40) ceramics were fabricated from their oxide mixture via a direct sintering process without involving the calcination step. Different levels of excess PbO (0,10 and 20 mol percent) were used to check its effect on microstructure and thus the electrical properties of the PLZT ceramics. The reaction and densification behavior of the oxide mixtures for the PLZT ceramics were monitored by using a dilatometer. The electrical properties of the PLZT ceramics and their relationships with the processing parameters and excess PbO levels were characterized and discussed.
