A carbon dioxide gas sensor was studied as a function of temperature and CO₂concentration In the Li₂ZrO₃ system. Lithium zirconatet(Li₂ZrO₃) was synthesized by the heat-treatment of zirconia(ZrO₂) and Lithium carbonate(Li₂ZrO₃). The specimens were prepared both as bulk disks. 10mm in diameter and 1.0mm thickness, and thick films on an alumina substrate. Lithium zirconate readily responded to CO₂ concentration from 0.1% to 100% in the range of 450℃ to 650℃. The sensitivity to CO₂ was dependent on the measuring temperature. Lithium zirconate(Li₂ZrO₃) decomposes into Li₂ZrO₃ and ZrO₂ after the reaction with CO₂ in the range of 450℃ to 650℃, and Li₂ZrO₃ changes into Li₂O and CO₂ above 650℃. The material showed difficulty with reversibility and recovery. The optimum temperature for the highest sensitivity is around 550℃.
