"This report describes a Bureau of Mines investigation into the standard Gibbs energies of formation agf deg., for NiCr2O4 (nickel chromite) and CoCr2O4 (cobalt chromite). High temperature galvanic cells employing stabilized ZrO2 (zirconia) as the solid electrolyte were used to measure the open-circuit potentials for the cell reactions, and equilibrium oxygen pressures for the Ni-Cr2O3-NiCr2O4- O2 system were determined from the electromotive force (emf) measurements." - NIOSHTIC-2 NIOSHTIC no. 10005438
