Abstract

Large Na 0.5 K 0.5 NbO 3 ( NKN ) piezoelectric single crystals were obtained by seed‐free solid‐state crystal growth method, which is a traditional sintering grain growth process, with LiBiO 3 used as a sintering aid. The largest dimension of the single crystals obtained was 11 mm × 9 mm × 3 mm. In ...
