Abstract
The electrical behavior of Li2ZrO3 ceramics was studied as a function of te mperature and CO2 concentration. The phases of Li2ZrO3 were synthesized by the solid-state reaction of ZrO2 and Li2CO3 at 1300 degreesC for 6 h. The s pecimens were made by the thick film fabrication process on 96% alumina sub strates. The electrical resistance readily responded to CO2 concentrations ranging from 0.1% to 100% at 550 degreesC. The variation of the electrical behavior is related to the change of the phases and conducting path. Li2ZrO 3 decomposed into Li2CO3 and ZrO2 after the reaction with CO2 below 650 deg reesC, and Li2CO3 decomposed into Li2O and CO2 at and above 650 degreesC.
