[en] The CaTiO₃-modified [(K_0.5Na_0.5)_0.96Li_0.04](Nb_0.91Sb_0.05Ta_0.04)O₃ lead-free piezoelectric ceramics were prepared using normal sintering for improving the temperature stability of (K_0.5Na_0.5)NbO₃-based ceramics. The effects of the CaTiO₃ on the temperature stability and piezoelectric properties of the ceramics were systematically studied. These results show that the CaTiO₃-modified [(K_0.5Na_0.5)_0.96Li_0.04](Nb_0.91Sb_0.05Ta_0.04)O₃ lead-free piezoelectric ceramics possess good temperature stability in the polymorphic phase transition below room temperature, and also exhibit high piezoelectric properties (d₃₃=263 pC/N and k_p=50%) when the ceramics were poled at an optimum poling temperature. These results indicate that the ceramic is a promising candidate material for lead-free piezoelectric ceramics
