The YBa2Cu3Ox (123) superconductor has been prepared by a new method using the ternary precursors BaCuO2 and Y2CU2O5. The BaCuO2 is prepared by calcining a mixture of BaCO3 and CuO at a temperature of ≈850°C in flowing oxygen at reduced total pressure, followed by ambient-pressure heating at ≈925°C. The Y2CU2O5 is synthesized by a solid-state reaction between Y2O3 and CuO in ambient pressure at ≈950°C. A stoichiometric mixture of BaCuO2 and Y2CU2O5 is heated to ≈950°C to form 123. The reaction between Y2CU2O5 and BaCuO2 is very fast and results in nearly phase-pure 123 in a short period.
