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 YBa₂Cu₃O_x. 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.
