Growth features of grains in ceramics based on titanates and niobates of alkali and alkaline earth metals

摘要

The article presents the results of research of the grains surfaces piezoelectric ceramics with ABO(3)composition using scanning electron microscopy and atomic force microscopy. The dependences of the shape and size of the grains on the cation in position A are detected. Growth steps are observed on the surface of the grains. Domain walls on such grains are perpendicular to the growth steps.
