Abstract

본 발명은 니켈을 함유한 납계 페로브스키트형 복합 화합물을 함유하는 유전체 세라믹 조성물에 관한 것으로, 니켈의 함량이 화학 양론 비보다 소량임을 특징으로 한다.
유전체 세라믹 조성물은, 하기 화학식(1);
Pb[Ni(1-x)/3B+5 2/3]a[Ni(1-y)/2B+6 1/2](1-a)O3(1)
(식 중에서, B+5는 +5가를 가진 원소들로부터 선택된 적어도 1종의 원소를 나타내고, B+6은 +6가를 가진 원소들로부터 선택된 적어도 1종의 원소를 나타내며, 0x1, 0y1 및 0≤a≤1이다)로 표시되는 납계 페로브스키트형 복합 화합물을 α몰%(0α≤100)의 양으로 함유하며, 이때 니켈의 함량은 화학 양론 비보다 소량인 γ몰%(0γ≤20)이다(단, γ=α×(a×x×1/3+(1-a)×y×1/2).
유전체 세라믹 조성물은 고유전율을 지니면서, 거의 일정한 용량-온도 특성(capacity-temperature characteristic)을 지닌다.
