Comparison of (K_0.5Na_0.5)NbO₃ Single Crystals Grown by Seed-Free and Seeded Solid-State Single Crystal Growth.

ABSTRACT: (K_0.5Na_0.5)NbO₃-based piezoelectric ceramics are of interest as a lead-free replacement for Pb(Zr,Ti)O₃. In recent years, single crystals of (K_0.5Na_0.5)NbO₃ with improved properties have been grown by the seed-free solid-state crystal growth method, in which the base composition is doped with a specific amount of donor dopant, inducing a few grains to grow abnormally large and form single crystals. Our laboratory experienced difficulty obtaining repeatable single crystal growth using this method. To try and overcome this problem, single crystals of 0.985(K_0.5Na_0.5)NbO₃-0.015Ba_1.05Nb_0.77O₃ and 0.985(K_0.5Na_0.5)NbO₃-0.0
