- 中文摘要: To prepare the YBa/sub 2/Cu/sub 3/O/sub y/ (Y-123) and(Bi,Pb)/sub 2/(Sr,Ca)/sub 4/Cu/sub 3/O/sub y/ (Bi-2223) superconductive materials, coprecipitation was used with 8-hydroxyquinoline (oxine) as precipitant to ensure complete precipitation. Various aspects of competitive reactions such as dissociation, precipitation, complex formation and association in the aqueous solution system containing metal ions, oxinate ion and diethylamine species have been explored in order to discover the optimal coprecipitation conditions of the title system. Experiments were conducted to confirm these conditions.
