The weight gain, surface morphology, surface elements, composition, and structure for the Li₂ZrO₃ samples were investigated after air exposure for various times at room temperature The Li₂CO₃/ZrO₂ layers were formed by the reaction between Li₂ZrO₃ and CO₂ due to Li⁺ ion segregation to the surface. Furthermore, the release of CO₂ occurred by reacting the produced Li₂CO₃ with the absorbed H₂O at temperatures above 423 K.
