Abstract

Pt/Na+ ion conductive ceramics thin film/Pt/carbonate a2CO3:BaCO3=1:1.7 mol) structure micro CO2 sensors were prepared and their sensing properties were investigated. The thin film Na+ ion conductors formed by using RF magnetron sputtering technique. The chemical composition of thin film Na+ ion conductor was found to be same as that of NASICON(x=2). The nernst slope of 57 mV/decade or CO2 concentration range between 1,000 to 10,000 ppm was observed at the operating temperature of 400 °C.
