“…When the temperature was increased from 235 to 350 °C, the samples presented a third loss of weight. The weight loss produced at these temperatures could be attributed to a second dehydroxylation process, in this case due to the Li−OH species produced during the water reaction with the ceramic. , It should be mentioned that according to the weight lost in these two thermal processes, lithium hydroxylation seems to be favored over the zirconium hydroxylation. Finally, a decarbonation process was observed at temperatures higher than 400 °C.…”

Lithium metazirconate with and without potassium were synthesized by solid-state reaction. Different water vapor sorption experiments were performed in the presence and absence of CO 2 to elucidate the different physicochemical processes produced. In the absence of CO 2 , initial results showed that potassium addition enhances significantly the water sorption on the Li 2 ZrO 3 ceramic. Then, it was shown that water vapor is trapped by two different mechanisms on Li 2 ZrO 3 , adsorption and absorption. When CO 2 was added to water vapor flow the Li 2 ZrO 3 reactivity increased significantly. On the basis of these results, a possible K-Li 2 ZrO 3 -H 2 O-CO 2 reaction mechanism was proposed; as a first step Li 2 ZrO 3 and H 2 O must react producing some Li-OH and Zr-OH species. Then, CO 2 must react with hydroxyl species (mainly Li-OH), producing lithium carbonate. Finally, the presence of this new specie must favor a higher water adsorption.
