摘要：

We synthesized lithium zirconate using solid-state reaction and analyzed thermal properties (TG/DTA) of starting materials and the synthesized one. When Li2ZrO3 powder was exposed to CO2 environment at 500 degrees C, 93% of the theoretical absorption weight was gained within 280 min with fairly high sorption rate. Almost all the absorbed CO2 was generated by heating the sample to 800 degrees C. We also investigated densification behavior of Li2ZrO3 under CO2 environment. By sintering Li2ZrO3 at 760 degrees C using 2-step process, we obtained dense product, composed mainly of Li2ZrO3 and ZrO2, with relative density of 92%.
