Abstract

The thick type sensor having Pt/Na super ionic conductor(NASICON) Pt/Na₂SO₄/Pt catalyst system for SO₂ gas sensing was fabricated by screen printing method. The phases of NASICON with the variation of sintering temperature (1050°C, 1150°C, 1250°C) and sintering time (1.5hr, 2.5hr, 3.5hr) were investigated by XRD. The variation of electromotive force of the sensor with SO₂ concentration and operation temperature were also investigated. The major phase of NASICON film sintered at 1150°C for 3.5hr was sodium zirconium silicon phosphate (Na₃Zr₂Si₂PO₁₂). The Nernest's slope of NASICON sensor for SO₂ gas with the variation of concentration from 10 to 100 ppm was 176.12 mV/decade at the operating temperature of 500°C. The increase of oxygen partial pressure was not affected to the variation of Nernest's slope.
