MASTER CURVE MODEL FOR CHARACTERIZATION OF DECOMPOSITION AND DENSIFICATION BEHAVIOR OF PbAlNbO3-PbZrTiO3 CERAMICS

Abstract

In this study, decomposition and densification behavior of PbAlNbO3-PbZrTiO3 (PAN-PZT) ceramics were characterized for powder injection molding process. Thermal gravity analysis and in-situ dilatometer experiment were carried out to construct master curve. Based on master curve model approach, one-combined master debinding curve (MDC) and master sintering curve (MSC) were constructed for piezoelectric PAN-PZT ceramics. Derived curves matched well with the experimental data. Process optimization and material development will be conducted based on characterization of master curve parameters.
