Monoelinie Li2ZrO3 structure is the proliferation materiall; tetragonal Li2ZrO3 phase is good at the adsorption of CO2 at high temperature,and Li2ZrO3 is also excellent lithium-ion conductor. This paper focused on the research of preparation and characteristics of Lithium ion conductive materials Li2ZrO3. A citrate sol-gel method was applied to synthesize nanocrystalline Li2ZrO3 materials . The structure and morphologies were characterized by X- ray diffraction and scanning electron microscopy. The results showed that the crystallite size of Li2ZrO3 was about 20 nm by Using this method. The ratios of CA to zirconium is four, the calcinations temperature between 750℃ to 850℃,calcinations time between 150 min to210min can get the sample of tetragonal Li2ZrO3 phase.
