The Sensor Response for CO Gas of $LaMO_3$ and $LaFe_{1-x}CO_xO_3$ in Perovskite Type Oxides

Perovskite형 산화물 $LaMO_3$와 $LaFe_{1-x}CO_xO_3$의 일산화탄소가스에 대한 센서 응답 특성

The oxides in perovskite type, $LaMO_3$ (M=Ni, Cr, Fe, Co), compared with gas sensors which have been used, were synthesised and then examined sensor response comparatively in order to make a thick film gas sensor having a good gas selectivity, durability and simple manufacturing. The oxides in perovskite type, $LaFe_{1-x}O_3$ (x=0.2, 0.4, 0.6, 0.8), which a part of Fe was replaced with Co, were examined with regard to their electric resistance with variable temperature and sensor response for carbon monoxide gas.
