Crystallographic Orientation of (Li,Na,K)NbO₃ Lead-Free Piezoelectric Crystal

Abstract:

Li,Na,K)NbO₃ (LNKN) crystals were grown by an infrared convergence-type floating zone (FZ) method using SrTiO₃ seed crystals to control the crystallographic orientation. The crystals were grown along the [10 direction of SrTiO₃ seed crystal. It was a critical condition for the crystal growth that the descending speed of an upper shaft in the FZ furnace was faster than that of the lower shaft. The grown crystal sizes were about 10 mm in length and 5 mm in diameter. A relation between the Li content and T_c was investigated, and the result was compared with the case of polycrystalline ceramic samples.
