Abstract

본 발명은 자연광물인 규조토(Diatomaceous earth)를 단독으로 사용하거나 금속산화물과 일정 비율로 복합체화된 상태로 사용하여 제조된 세라믹 다공체 및 이 다공체를 원료로 하여 제조된 저항-습도 특성곡선의 대수직선성이 우수하고 감도가 뛰어날 뿐아니라 기존에 금속산화물만을 원료로 사용하여 제조하던 경우에 비해 제조원가 절감의 효과까지 나타내는 다공성 세라믹 감습소자에 관한 것이다.
제1도는 본 발명에 따라 다공성 세라믹 감습소자를 1000℃로 열처리하여 제조한 후, 25℃에서 상대습도 변화에 따른 저항-습도 특성곡선의 변화를 도시한 그래프이다.
제2도는 본 발명에 따라 다공성 세라믹 감습소자를 1100℃ 및 1200℃로 각각 열처리하여 제조한 후, 25℃에서 상대습도 변화에 따른 저항-습도 특성곡선의 변화를 도시한 그래프이다.
