Abstract Oxygen nonstoichiometry in high-T{sub c} superconductor YBa{sub 2}Cu{sub 3}O{sub y} was studied by vapor pressure measurements in a closed volume in the temperature range 673 to 1173 K and oxygen pressure up to 1 atm. P-T-X phase relationships were derived from the vapor pressure scanning of the solidus surface. Analytical representation of isothermal, isobaric, and isoplethal (X{sub s} = const) sections of the P-T-X diagram is given. Partial thermodynamic functions of oxygen were calculated in the oxygen nonstoichiometry range 6.30 to 6.85.
