Abstract
Single crystals of 0.75(Bi1/2Na1/2)TiO3-0.25SrTiO3 have potential for use in piezoelectric actuators because of their large values of electric field-induced strain. Single crystals of 0.75(Bi1/2Na1/2)TiO3-0.25SrTiO3 have been prepared by solid-state single crystal growth, but growing large crystals is difficult due to matrix grain growth. Previous experiments with 0.95(Bi1/2Na1/2)TiO3-0.05BaTiO3 showed that doping with ZrO2 reduced matrix grain growth but also reduced single crystal growth. In this work, 0.75(Bi1/2Na1/2)TiO3-0.25SrTiO3 is doped with small amounts of ZrO2 and the effect on both single crystal and matrix grain growth is examined. ZrO2 addition has a minor effect on single crystal and matrix grain growth.
