Subsolidus phase equilibria of the CuO – SrO – ZnO pseudoternary system in air at 900 °C

Subsolidus phase equilibria of the CuO – SrO – ZnO pseudoternary system in air at 900 °C

The subsolidus phase equilibria of the CuO – SrO – ZnO system were determined at 900 °C in air. The pseudoternary section does not contain ternary oxide phases but is made of 5 three-phase regions and 2 narrow two-phase regions linked to a Sr14Cu24-xZnxO41-y solid solution. The maximum solubility of...
