Highly dense and homogeneous yttria (Y 2 O 3 ) thin-wall tubes have been successfully fabricated by applying tape-casting and radial magnetic pulsed compaction (RMPC) followed by thermal sintering. Since a homogeneous density distribution was obtained in the RMPCed compact, by using the Y 2 O 3 -based tape instead of a stuck of raw powder, cracking and bending were inhibited throughout the process up to the final sintered body. The relative density of the resultant tube reached 99.9%, and the structure was very fine with grain sizes of 2$5 mm. Moreover, when the granulated powder was used as the precursor of the tape, the thermal densification was promoted due to its enhanced sinterability as compared to the raw powder.
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.
