Abstract
The effects of Li2O, Bi2O3, CdO, and V2O5 on sintering temperature and electromechanical properties were investigated for PZT (lead zirconate titanate) ceramics. In order to reduce the sintering temperatures further, complex additives of Li2O-Bi2O3-CdO (LBC) were employed. LBC will melt to form liquid at low temperature and promote the densification of the ceramics. The mass transport process of the solution and reprecipitation made the element distribution uniform and led to further densification of the ceramics. The electromechanical properties of the PZT ceramics were not affected because the additives did not have harmful impurities
