Abstract:Tantalum metal was prepared by Solid Oxygen-ion Conducting Membrane (SOM) technology from Ta2O5 directly in molten CaCl2. Through reaction mechanism of the metal-oxide-electrolyte three-phase interline (3PIs), the influence of pellets microstructure on the electrolysis process and products morphology were discussed. The results demonstrate that forming pressure, particle size and porosity of cathode pellets are significant factors for three-phase interline during electrolysis process. It was found that the big… 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.
