Effect of microwave sintering on KNN-based lead free ceramics

Abstract

Microwave sintering has been known as the effective method to prepare ceramics. In this study, the microwave sintering method was used to synthesize 0.96(K_0.5Na_0.5)_0.95Li_0.05Nb_0.93Sb_0.07O₃-0.04CaZrO₃ 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.

Keywords:

• Piezoelectric properties
• (K_0.5Na_0.5)NbO₃
