Preparation of NASICON disk by tape casting and its CO2 sensing properties

摘要：

　　In this work,NASICON-type disks with the formula,Na3Zr2Si2PO12 were prepared by non-aqueous tape casting method.The effect of the dispersant on the slurry viscosity was investigated,triethanolamine was found to be an effective dispersant for NASICON slurry.The correlation between the overall conductivity and the sintering conditions (temperature and time) for the NASICON disk was also studied.Green tapes were calcined at 900℃,1000℃,1100℃ for 6h and 12h,respectively.Results revealed that the overall conductivity increased with the increasing of the sintering temperature and decreased with the increasing of the sintering time.The segregation of resistive monoclinic ZrO2 phase was examined to have a negative effect on the overall conductivity.The CO2 sensor using NASICON disk and Li2CO3-BaCO3 complex thick film was fabricated and evaluated,the sensitivity was about 82.9 mV/decade at 450℃.
