A ceramic composite with continuous phases of α-alumina and the oxygen-ion conducting ceramic, such as zirconia, is exposed to a vapor containing an alkali-metal oxide, such as an oxide of sodium or potassium.

This alkali metal oxide is preferably sodium oxide and/or potassium oxide, and the concentration of the alkali metal oxide is 0.002 ≤ Na2O ≤ 0.1 % by weight and/or 0.002 ≤ K2O ≤ 0.1 % by weight.

The base is chosen from the following compounds: sodium hydroxide (NaOH), calcium oxide (CaO), potassium hydroxide (KOH), calcium carbonate Ca(OH)2.

However, the total sodium oxide (Na2O) content shall not exceed 40 % by mass.
