The thermodynamic properties of nonsuperconducting phases in the Y-Ba-Cu-O system are critically reviewed and those of YBa4Cu3Os.5 are estimated. With the aid of these data, subsolidus phase equilibria are calculated for a wide range of oxygen pressures and temperatures, and stability fields of the
Microstructural and X-ray analyses were carried out on the Y-Ba-Cu-O superconductor compound doped with nickel. It is shown that there is a limited solubility of nickel in YBa2Cu307\_ 6 with a resultant Tยข (midpoint) slightly below liquid nitrogen temperature. Partial melting caused a sharp supercon
