Abstract The sintering behavior and the electrical properties of sintered PZT ceramics using 2.45 GHz microwave energy were investigated. The ceramics were sintered between $1050 ~ 1130^{circ}C$ for 5 min. Sintered body with high density and good electrical properties were achieved as the sintering temperature increases. Above $1090^{circ}C$, however, the bulk density was decreased due to the volatilization of PbO component, and also electrical properties were decreased. The relative dielectric constant, mechanical Quality factor, electro- mechanical coupling factor of microwave sintered body at $1090^{circ}C$ without PbO atmosphere were 1900, 80, 0.53 respectively, which were comparable to conventional sintering values. The sintering process completed within 20 min using microwave hybrid energy. The processing time and the amount of energy con-sumption could be reduced by microwave hybrid energy assisted rapid sintering.
