Abstract

Microstructural engineering in conjunction with compositional design has been used for tailoring the properties of piezoelectric materials. In piezoelectric ceramics, the plate-like particles are used for the seed materials in order to realize the textured microstructures. In this study, the seed crystals are synthesized by simple molten salt synthesis (SMSS), using a generalized rule for driving the abnormal grain growth in (K,Na)NbO₃ (KNN)-based ceramics. Furthermore, the textured ceramics are successfully produced in Ba-doped KNN materials, using the seed crystals which are grown by SMSS. Consequently, the textured ceramic shows the Lotgering factor of 92% and the piezoelectric constant (d₃₃) which is similar to that of a single crystal. It is suggested that the excess donor ratio must be considered to obtain the seed crystals (synthesized by SMSS) and textured microstructures in KNN-based ceramics.
