摘要：
A new sintering aid designed for a commercial type I PZT (lead zirconate titanate) allows sintering at temperatures as low as 800 degreesC. The additive contains PbO and Cu2O and works by forming a liquid phase. The amount of additive needed to reduce the sintering temperature below 900 degreesC causes a certain deterioration of the piezoelectric properties in comparison with the original composition, however. The present work describes the optimisation of the sintering aid in order to obtain low dielectric loss and high piezoelectric activity at sintering temperatures close to 1100 degreesC. This is particularly relevant to co-fired multilayer components.
