Summary

The high temperature phase equilibria in the Cu2O-Ga2O3-In2O3 system was studied. In particular, the thermodynamic stability of the CuGaO2 phase with the delafossite structure was determined as a function of temperature and oxygen partial pressure. The experimental results compared favorably to theoretical calculations based on thermodynamic data. Variations in the unit cell parameters with the isovalent substitution of In3+ were measured by diffraction methods. Finally, the crystal structure of single phase CuGaO2 was refined by Rietveld analysis with a = 2.976 Å and c = 17.160 Å with an X2 value of 1.600.
