Abstract

NASICON sensors that the NASICON electrolytes with various CaO amounts were sintered at low temperature($900^{\circ}C$), were fabricated to improve $CO_2$ sensitivity and stability in sensing behaviors. The manufactured device was shown good sensing characteristics and stability of output electromotive force at $250^{\circ}C$, comparatively low operating temperature.

$CO_2$ 가스 감도를 높임과 동시에 감지거동을 안정화시키기 위하여 여러 함량의 CaO가 함유된 NASICON 전해질을 낮은 온도에서 소결하여 NASICON 센서를 제작하였다. 제조된 소자는 비교적 낮은 동작온도인 $250^{\circ}C$정도에서도 양호한 감도와 안정된 출력특성을 나타내었다.
