  • LEAD-FREE KNN-BASED PIEZOELECTRIC CERAMIC MATERIAL WITH TEXTURING, AND METHOD OF MAKING THE SAME
    Publication number: 20220069196
    Abstract: A lead-free KNN-based piezoelectric material represented by the composition formula (KaNabLic)(NbdTaeSbf)Og, where 0.4?a?0.5, 0.5?b?0.6, 0.01?c?0.1, 0.5?d?1.0, 0.05?e?0.15, 0.01?f?0.09, 1?g?3. In one embodiment, the lead-free KNN-based piezoelectric material has a d33>300 pm/V and a Tcurie>250° C. In one embodiment, the d33 and Tcurie of the lead-free textured KNN-based piezoelectric material can be adjusted by creating phase boundaries of (i) orthorhombic to tetragonal (O-T), (ii) rhombohedral to orthorhombic (R-O), and (iii) orthorhombic to tetragonal (O-T). In one embodiment, the lead-free KNN-based piezoelectric material is textured with NaNbO3 or Ba2NaNb5O15 seeds which are platelet or acicular shaped. In one embodiment, the amount, orientation, or particle size distribution of the NaNbO3 or Ba2NaNb5O15 texturing seeds in the lead-free textured KNN-based piezoelectric material can be altered.
