Abstract

본 발명은 온도 센서인 NTC 써미스터(Negative Temperature Coefficient Thermister; 감온 온도 센서)의 저온 제조 방법 및 그 조성물에 관한 것으로서, 산화망간-산화니켈-산화지르콘-산화아연계에 B2O3-SiO2계외 프리트를 첨가한 조성물, 또는 산화망간-산화니켈-산화코발트계에 있어서, 고가의 Co3O를 저가의 CuO로 치환하여 대체시킨 조성물을 NTC 써미스터용 조성물로 사용하는 것에 의하여 소결 온도를 950∼1150℃로 낮출 수 있으면서도 우수한 온도센서 특성을 갖는 NTC 써미스터를 제조할 수 있게 한 신규 유용한 발명이다.
