Abstract

Reaction of Y2O3, BaCO3 and CuO for 4 h at 800°C in flowing O2 with a total pressure of about 2.7×102Pa, followed by cooling in O2 at ambient pressure, has produced phase-pure orthorhombic YBa2Cu3Ox. Keeping the ratio of O2 to evolved CO2 above 50 was necessary to ensure phase purity. The resultant powder yielded pressed and sintered pellets with improved super-conducting properties.
