Lz. Zhao et al., ELECTROCHEMICAL SYNTHESES OF BA-K-BI-O CRYSTALS IN HOT ALKALINE-SOLUTION AND WATER-RICH MELTS, Physica. C, Superconductivity, 282, 1997, pp. 721-722
Non-superconducting and superconducting Ba-K-Bi-O crystals were synthe
sized electrochemically from hot aqueous solution and water rich melts
over a range of temperatures (80-210 degrees C). The resulting Ba-K-B
i-O crystals were characterized by using XPS, XRD and magnetic method.
