Abstract

본 발명은 비금속 물질을 내부전극으로 사용하여 저산소 분압(환원성 분위기)하에서 소결하였을 때 양호한 절연성과 높은 유전율을 갖는 비환원성 유전체 자기조성물에 관한것으로, BaTiO3, CaZrO3, 및 SrZrO3의 3성분계를 기본으로 하여 MgO, MnCO3, SiO2, Nb2O5등의 첨가제를 미량 사용하므로써 환원분위기하에서 소결하여도 양호한 절연저항과 고 유전율을 갖는 동시에 우수한 온도 특성(Temperature Coefficient of Capacitaince)를 갖는 비환원성 세라믹 유전체 자기조성물에 관한것이다.
