摘要: The electric-field-induced strain in 93%(Bi0.5Na0.5)TiO3–7%BaTiO3 polycrystalline ceramic is shown to be the result of an phase transformation from a pseudocubic tetragonal symmetry. High-energy x-ray diffraction used illustrate microstructural nature transformation. A combination induced unit cell volumetric changes, domain texture, and anisotropic lattice strains are responsible for observed macroscopic strain. This mechanism not analogous high lead-based morphotropic boundary systems. Thus, systems which appear cubic under zero field should excluded search lead-free piezoelectric compositions.
