Abstract

본 발명은 위치변위시스템 및 유전체 공진기 재료로 사용되는 고주파 유전체 자기조성물에 관한 것이다. 본 발명의 유전체 자기조성물은 Zr1-xSnxTiO4계 조성으로서, 이때 x는 몰비로 0.1 ≤ x ≤ 0.4이며, 이는 산화지르코늄(ZrO2), 산화티탄(TiO2), 산화주석(SnO2)의 원료분말을 혼합하여 1000~1200℃에서 하소하여 분쇄한 후 소정형상으로 성형하여 1500~1800℃의 온도에서 소성한 다음 냉각공정중 1250~1400℃에서 어닐링하고, 어닐링 후 상온에 이르기까지 급냉하는 제조방법에 의해 제조된다. 본 발명의 고주파 유전체 자기조성물은 향상된 품질계수(Q)와 유전율(k)을 나타낸다.
