Abstract:

The thermodynamic stability of K-beta-Al2O3 (KBA) has been determined by characterizing the equilibrium between K-- and K-″-Al2O3 using a potentiometric technique with yttria-stabilized zirconia (YSZ) as solid electrolyte. The cell allows an in situ check of the establishment and maintenance of the phase equilibrium by changing the composition of the KBA material reversibly. The activity of the potassium oxide dissolved in KBA amounts to (375°–600°C) from which the standard Gibbs free energy of formation of K-″-Al2O3 can be obtained as
