Abstract

The piezoelectric response of [110]-oriented, fine-grained BaTiO ₃ ceramics was investigated. It was found that an exposure of the BaTiO₃ compacts to high-pressure, high-temperature steam in an autoclave promoted the orientation of the sintered ceramics. As temperature in the autoclave increased, the orientation increased. A large small-field piezoelectric constant of d₃₃ = 517 pC/N was observed for the oriented BaTiO₃ ceramics with the grain size of 1.76 μm and the Lotgering factor of 85.3 %.
