Properties and Microstructure of PZT Ceramics Sintered by Microwave

Abstract

The feasibility of microwave sintering of lead zirconate titanate (PZT) ceramics was examined. Microwave sintering was performed at low temperature and short soaking time, using a heating control system with single mode cavity (2.45GHz). Higher density and electric properties were obtained compared with the conventional process, because the sintering reaction was accelerated by microwave radiation. Moreover, higher strength was obtained due to smaller grain size. The microwave sintering was expected to give both high strength and high electric properties.
