Cu2O,CuO/O2-/air Cu2In2O5, In2O3,Cu2O/O2-/air In,In2O3/O2-/Ni, NiO
Gibbs free energy of formation of solid Cu2In2O5 phase as well as that for
In2O3 and CuO oxides was determined in the temperature range from 973 K to
1372 K. The results obtained in this study were used to derive Gibbs free
energy change of the reaction of formation of the ternary compound from
respective oxides: 2CuO + In2O3 = Cu2In2O5 which is equal to:
ΔGf0,Cu2In2O5 = 33905 − 41.50T (±3600) Jmol−1. Standard
enthalpy of formation from elements ΔH0f,298 and standard enthalpy ΔS0298
derived for Cu2In2O5 phase by Second Law sigma plot are -1211 (±15) kJ
mol-1 and 493.20 (±10) J (K-1 mol-1). Oxygen potential diagrams for the
Cu-In-O system are also given at two temperatures. |
