The activities of Na 2 O and K 2 O dissolved in mixed‐alkali Na–K–(β+β″)‐Al 2 O 3 (NKBA) have been determined by using yttria stabilized zirconia (YSZ) as a solid electrolyte in the following galvanic cells:The approach enables to verify in situ the establishment and maintenance of the β/β″‐equilibrium, and to characterize it as a function of the phase composition of NKBA. The results can be expressed as follows:
