AbstractMicrowave sintering has been known as the effective method to prepare ceramics. In this study, the microwave sintering method was used to synthesize 0.96(K0.5Na0.5)0.95Li0.05Nb0.93Sb0.07O3-0.04CaZrO3 ceramics. The effect of holding time on the properties of ceramics was investigated. With the holding time of 30 min, the excellent piezoelectric properties (d33 = 286 pC/N) can be achieved.
