A new protonated oxide has been synthesized by ion exchange of lithium by proton in lithium metazirconate, Li 2 ZrO 3 . Easy and complete ion exchange has been achieved in acidic medium. Characterization of the protonated solid by means of X–ray powder diffraction and thermogravimetric analysis allow to propose the nominal formulation “H 2 ZrO 3 ”. However vibrational spectroscopy suggests that a more appropriate formulation would be as an oxyhydroxide ZrO(OH) 2 .
