The subsolidus phase relations of the SrO–Ta2O5–CuO system were investigated in air. The samples were equilibrated at 900 °C. The ternary oxide Sr3Ta2CuO9 compound is stable under these conditions. This phase presents a solid solution range, its actual composition being Sr3Ta2−xCu1+xO9+δ with 0.0 ≤ x ≤ 0.2.
Up to about 5 at.% Cu can be incorporated in the Sr3−xTa1+xO5.5+δ phase. Similarities with the SrO–Nb2O5–CuO system are discussed.
