Reactive sintering and piezoelectric properties of 0.94Bi<sub>0.5</sub>Na<sub>0.5</sub>TiO<sub>3</sub>–0.06BaTiO<sub>3</sub> ceramics with ZnO additive
Abstract:Bismuth sodium titanate (Bi 0.5 Na 0.5 TiO 3 , BNT) and its solid-solution with BaTiO 3 (BNTBT) are promising lead-free piezoelectric ceramics. Around the morphotropic phase boundary (MPB), the 0.94BNT0.06BT composition shows high piezoelectric performance. In this paper, we have investigated the effect of ZnO-doping on the reactive sintering and piezoelectric properties of 0.94BNT0.06BT ceramics. Bi 2 O 3 , anhydrous Na 2 CO 3 , TiO 2 (anatase), BaCO 3 and ZnO powders were wet ball-milled in ethanol, cold iso… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
