Abstract:Reaction of superconducting Y(Ba1.5Sr0.5)Cu3Oy (abbreviated as YS‐123) powder with water in a closed system at pH 7 and 25 °C, after 150 h, the concentration ratio of Y:Ba:Sr:Cu ion in the solution is 0.0025:1:0.33:0.0003. Mass equation of the reaction is similar to that of YBa2Cu3Oy (abbreviated as Y‐123). Leaching rate of the Ba ion is higher than that of the Sr ion at the beginning of the reaction, which reflects the basicity difference between these two alkaline earth elements. The initial rate equation is… 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.
