Investigation of affecting parameters of Electrophoretic deposition (EPD) method in (Bi0.5Na0.5)TiO3-Hexagonal BaTiO3 and their properties
October 1-6, 2017
Nowadays, eco-friendly materials have been attracting attention worldwide since the legislation of RoHS/WEEE directives in Europe. (Bi0.5Na0.5)TiO3-BaTiO3 (BNT-BT) systems are well known candidate of lead-free piezoelectric materials. However, BNT-BT systems have relatively low piezoelectric constant (d33 ~ 140 pC/N) which is difficult to apply in commercial products. In spite of this problem, BNT-BT systems have good potential because it is easy to apply mass production.
Electrophoretic deposition method (EPD) has good advantage in mass production because size and shape of green ceramics is easily controlled by control of electrode. Moreover, it is reported that EPD method can be fabricated textured ceramics using high magnetic field and texture technique is important in enhancing piezoelectric properties. Our final goal is making  oriented BNT-BT ceramics which have enhanced piezoelectric properties and appreciate for mass production.
