Abstract

본 발명은 나노크기를 갖는 티탄산바륨 입자 및 그의 제조 방법에 관한 것으로, 혼합비즈를 사용하여 균일분쇄와 분산효과를 동시에 얻을 수 있도록 하고, BaCO3 출발원료를 나노 분쇄한 후 나노크기의 TiO2와 혼합하는 방법을 사용하되, 1차 0.65mm, 1mm 혼합비즈와 1600rpm의 저속으로 고에너지밀에 의하여 분산을 행하고, 직렬로 연결된 0.1mm, 0.3mm 나노분쇄분산용 고에너지밀에 장입하여 분쇄 및 분산이 동시에 수행될 수 있도록 하는 발명에 관한 것이다. 아울러, 본 발명은 TiO2 출발원료를 사용하는 경우 루틸(58.2%) + 아나타제(41.8%)로 혼합된 것을 사용하여, 원활한 확산경로를 얻을 수 있도록 하고, 루틸 상의 높은 결정화도를 동시에 이용할 수 있도록 하여, 다른 출발원료를 즉 루틸이나 아나타제 단일상을 사용하는 것에 비하여 높은 반응성과 정방정비(c/a)를 얻을 수 있도록 하는 발명에 관한 것이다.
