Characterization of (Na0.47K0.47Li0.06)(SbxNb1−x)O3 ceramics prepared by molten salt synthesis method

In this study, (Na0.47K0.47Li0.06)(SbxNb1−x)O3 (NKL(SbxNb1−x)O3) powder is synthesized by molten salt synthesis method (MSS). The resulting products were characterized by the X-ray diffraction analysis (XRD) and scanning electron microscope (SEM) method. The (XRD) result of the corresponding ceramics proved the existence of the tetragonal phase symmetry near the morphotropic phase boundary. The SEM images indicated that the crystalline powder was well separated and no aggregate was present. The NKL(SbxNb1−x)O3 exhibited a strong compositional dependence and enhanced electrical properties while maintaining high Curie temperature. The results show that (NKL) (SbxNb1−x)O3 ceramics made by MSS method are promising candidates for lead-free piezoelectric materials.
