The subsolidus phase relations of the SrO–SbOx–CuO system were investigated in air. The samples were equilibrated at 1140K. Under these conditions, 7 binary oxide phases are stable: Sr2CuO3, SrCuO2, Sr14Cu24O41−δ, CuSb2O6, SrSb2O6, Sr2Sb2O7 and Sr7Sb2O12. The ternary section contains 10 three-phase regions.
A new ternary oxide phase with an approximate Sr3Sb2CuO9 composition of was identified. It structure is related to that of Sr8W3CuO18. This phase is not superconducting above 2K. Instead, the magnetic susceptibility indicates onset of weak ferro- or ferrimagnetism at T≈30K.
