Abstract:(Ba 0.85 Ca 0.15 )(Zr 0.1 Ti 0.9 )O 3 (BCZT) powder was synthesized by a solid-state reaction method, then the ceramics were fabricated by gel-casting and diepressing routes, respectively. Piezoelectric coefficient (d 33 ) was measured by the d 33 m ; Planar mode electromechanical coupling coefficient (k p ), dielectric loss (tand) and relative permittivity (e r ) were measured by the impedance analyzer. Results of measurements showed that in the range of tested sintering temperature (1300-1500°C), gel-casting… 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.
