Notes:
(1-x)(K0.44Na0.52Li0.04)(Nb0.84Ta0.10Sb0.06)O3-xSrTiO3 (KNNT-ST) lead free piezoelectricceramics have been synthesized by a solid state reaction method. The effect of SrTiO3 content on thepiezoelectric properties, sintering behavior and microstructure of (1-x) KNNT-x ST ceramics wasinvestigated. The experimental results showed that the addition of SrTiO3 can restrain the volatilization ofNa ions and K ions and improve relative density of the samples. A morphotropic phase boundary betweenorthorhombic and tetragonal phases is found in the composition range of 0.03〈x〈0.05. The piezoelectricproperties can be enhanced for (1-x) KNNT-x ST ceramics near the morphotropic phase boundary
