The effect of sintering condition on structure,microstructure,and ferroelectric properties of(K_(0.44)Na_(0.52)Li_(0.04))(Nb_(0.86)Ta_(0.10)sb_(0.04))-O_(3)(KNL-NTs)has been *** powders have been synthesized by the solid-state reaction method and sintered at different temperatures(1115℃,1125℃,and 1140℃).Then,samples were characterized by thermogravimetric analysis,X-ray diffraction,scanning electron microscopy,and impedance *** XRD results,the perovskite structure and small peaks corresponding to a secondary phase were *** processed at the highest temperatures showed higher densities and good piezoelectric properties(d_(33),K_(p),and K_(t)),particularly specimens sintered at 1125℃ presented the highest piezoelectric performance.
