Novel multi-iron-sequence R-type hexagonal ferrites, composites and articles comprising R-type hexagonal ferrites, and methods of making same
In one aspect, the R-type ferrite has the formula: Me '3Me2TiFe12O25, where Me' is at least one of Ba < 2 + > or Sr < 2 + >, and Me is at least one of Co < 2 + >, Mg < 2 + >, Cu < 2 + >, or Zn < 2 + >. In another aspect, a composite material or article comprises an R-type ferrite. In yet another aspect, a method of making an R-type ferrite includes: grinding a ferrite precursor compound comprising oxides of at least Fe, Ti, Me, and Me 'to form an oxide mixture; wherein Me'comprises at least one of Ba < 2 + > or Sr < 2 + >; me is at least one of Co < 2 + >, Mg < 2 + >, Cu < 2 + > or Zn < 2 + >; and calcining the oxide mixture in an oxygen atmosphere or an air atmosphere to form the R-type ferrite.
在一个方面中，R型铁氧体具有式：Me'3Me2TiFe12O25，其中Me'为Ba2+或Sr2+中的至少一者，以及Me为Co2+、Mg2+、Cu2+或Zn2+中的至少一者。在另一个方面中，复合材料或制品包含R型铁氧体。在又一个方面中，制造R型铁氧体的方法包括：对包含至少Fe、Ti、Me和Me'的氧化物的铁氧体前体化合物进行研磨以形成氧化物混合物；其中Me'包括Ba2+或Sr2+中的至少一者；Me为Co2+、Mg2+、Cu2+或Zn2+中的至少一者；以及在氧气氛或空气气氛中对氧化物混合物进行煅烧以形成R型铁氧体。
