The subsolidus phase relations of the SrO-In2O3-CuO system were investigated at 900 °C in air. Under these conditions, five binary oxide phases are stable: Sr2CuO3, SrCuO2, Sr14Cu24O41, In2Cu2O5 and SrIn2O4. The pseudo-ternary section is characterised by six three-phase regions and is dominated by the SrIn2O4 phase, which is in equilibrium with all other phases. No Sr equivalents of the Ca8In2Cu4O15, Ca9In14Cu2O32, Ba2In2CuO6, Ba2InCuO4.5 or Ba3In4Cu3O12 phases were formed.
