(1-x)(K0.44Na0.52Li0.04)(Nb0.84Ta0.10Sb0.06)O3-xSrTiO3 Lead Free Piezoelectric Ceramics
(1-x)(K0.44Na0.52Li0.04)(Nb0.84Ta0.10Sb0.06)O3-xSrTiO3 (KNNT-ST) lead free piezoelectric ceramics have been synthesized by a solid state reaction method.The effect of SrTiO3 content on the piezoelectric properties,sintering behavior and microstructure of (1-x) KNNT-x ST ceramics was investigated.The experimental results showed that the addition of SrTiO3 can restrain the volatilization of Na ions and K ions and improve relative density of the samples.A morphotropic phase boundary between orthorhombic and tetragonal phases is found in the composition range of 0.03<x<0.05.The piezoelectric properties can be enhanced for (1-x) KNNT-x ST ceramics near the morphotropic phase boundary.
