The subsolidus phase relations of the SrO–SbOx–CuO system were investigated in air. The samples were equilibrated at 1140 K. 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 2 K. Instead, the magnetic susceptibility indicates onset of weak ferro- or ferrimagnetism at T ≈ 30 K.
