Abstract

Phase equilibria in the system SrO-CaO-CuO have been studied under high oxygen pressures. The recently discovered non-superconducting binary phase, Sr_0.74(3)CuO₂, which is stable only under high oxygen pressure, forms a complete range of solid solutions with the structurally related phase, Ca_0.81(1)CuO₂. These materials have complicated superstructures and may form a family of Vernier phases, such as was found in Sr_0.74(3)CuO₂. Stabilities and oxygen stoichiometries of tetragonal Sr_2-2xCa_2xCuO_3+δ (0.0 ≤ x ≤ 0.1) and Sr_14-14xCa_14xCu₂₄O_38+δ (0.0 ≤ x ≤ 0.5) solid solutions under high oxygen pressures are also discussed.
