A new coprecipitation technique for the preparation of superconducting oxides

The high-temperature superconductors YBa 2Cu 3O 7−δ and Bi 2Sr 2CaCu 2O y, have been prepared by a new coprecipitation route using 8-hydroxy quinoline as the precipitating agent. The method is significant because it can be used for preparing the superconductors with predetermined low levels of impur...

Zusammenfassung:The high-temperature superconductors YBa 2Cu 3O 7−δ and Bi 2Sr 2CaCu 2O y, have been prepared by a new coprecipitation route using 8-hydroxy quinoline as the precipitating agent. The method is significant because it can be used for preparing the superconductors with predetermined low levels of impurity concentrations.
