Copper I 7400 Low-Temperature Synthesis of La2CuO4 with the T'-Structure from Molten Hydroxides. -The title compound is prepared by reaction of a stoichiometric mixture of La2O3 and Cu in a eutectiv KOH/NaOH melt (350°C, argon stream, alumina crucible, 14 d). The well-crystallized product obtained by this method has the Nd2CuO4 type (T') structure, while La2CuO4 prepared by conventional solis state reaction at 900°C in air has a distorted K2NiF4 type (O) structure. -(IMAI*, Y.; KATO, M.; TAKARABE, Y.; NOJI, T…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
