Abstract:

Additions of V2O5 from 0.1 to 8.0 wo to a coprecipitated PbZr.53 Ti.47 O3 ceramic promoted rapid densification below 1025 C, eliminating the need for PbO atmosphere control. Dielectric properties were found to be dependent on the amount of V2O5 added and on the microstructure developed, but were comparable to reported values for this PZT composition for additions of V2O5 or 1.5 WO. The indicated densification mechanism is one of activated sintering catalyzed by generation of oxygen defects on decomposition of the V2O5.
