加稀土元素氧化物或铭與稀土元素氧化物,可在125。(:高温 環境中控制·電阻變化。 然而’根據上述論文和專利申請公告所描述的方法,由 於游離水☆性鋇離子容易保留在原料與燒結物巾,黏合劑 進行膠凝化,破壞模製性,而且未進行反應之稀土元素的 氧化物會殘留。結果,帛製體因為吸濕而潤脹,在高濕度 ί哀境中產生新的性能問題。本發明者和其它人所進行的試 驗已釐清此等事實。 發明概述 因此本發明一個目的是提供一種具有負電阻溫度係數 的半導|±陶瓷和種負溫度係數熱敏電阻器,它們在高濕 度環境中具有良好的模製性與高可信度。 為達成刖述目的,在本發明具有負電阻溫度係數的半導 性陶瓷中,添加約O.iSM莫耳百分比的ΑΜη〇3 (八表示 Ca、Sr、Ba、La、Pr、Nd、Sm、Eu、Gd、Tb、^與
