The LaOLs-BaO-CuO pseudo-ternary phase diagram at 200 bar oxygen pressure was explored by a solid-state reaction at 980"C of numerous compositions. The phases which formed have been identified by X-ray diffraction. Significant differences from phases formed in air are noticed. BaCuO2 and Ba2CuO3 arc
