Using a spin-forming-extended method, which is one of the template grain growth methods, one-directional grain-orientation control was performed in (Sr,Ca)2NaNb5O15 (SCNN) ceramics. Rod like templates were prepared by the one-step flux method using the mixed salts of KCl and NaCl. In order to obtain the SCNN templates with a high aspect ratio, the two-step flux method in which Sr0.95Ca0.05Nb2O6 powder is utilized as the precursor was also examined. From these templates, the rectangular samples with c-axis orientation in the thickness direction were fabricated. The textured samples with an orientation factor of 0.9 and a remnant polarization of 7.4 µC/cm2 were obtained using the resulting templates from the two-step flux method.
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.
