Abstract

본 발명은 위치변위 시스템이나 유전체 공진기의 재료로 사용되는 고주파 유전체 자기조성물에 관한 것이다.
본 발명의 자기조성물은 주성분 Zr1-xSnxTi1+YO4(0.1〈X〈0.3, -0.1〈Y〈0.1)에 소결조제로 산화망간 0∼3 중량%와 산화니켈과 산화안티몬의 합이 0∼2 중량% 첨가되어 이루어진 조성으로, 이는 동 조성의 범위가 되도록 원료분말을 혼합하여 하소하고 분쇄한 후 소정형상으로 성형해서 1300∼1500℃의 산소분위기 중에서 소성함으로써 얻어진다. 본 발명의 고주파 유전체 자기조성물은 9GHz, 25℃에서 유전율 35이상, 품질계수 4000이상, Qxf값 40000 이상의 우수한 유전특성을 나타낸다.
