Abstract

Sol-gel processed NASICON-type with new compositions in the Na₃Zr₂-_(x/4)Si_2-xP_1+xO₁₂ system showed an improved sinterability with an increase in the x value. This is attributed to liquid phase sintering. This dense electrolyte system is suitable for the application as gas sensors. The CO₂ gas sensors using highly dense x = 0.667 (sample B) and x = 1.333 (sample C) samples show a stable EMF response in dry atmosphere which is very close to the theoretical value. Although a lower sensitivity and slower response were obtained in humid CO₂ gas, the sensor performance recovered after switching from humid gas to dry gas.
