    • The invention relates to a moulding of a sintered hexagonal ferrite material. This moulding is characterized in that the majority of the grains of the material have a monodomain structure. By virtue thereof, the loss factor tan delta of this material is much smaller than that of corresponding known materials if said material is used in the frequency range of 100 MHz or higher. The monodomain structure of this material is obtained, in particular, if the average grain size of the material is smaller than 2.8 micrometers. The average grain size preferably ranges between 1.4 micrometers and 2.5 micrometers. Preference is given, in particular, to those ferrite materials whose composition corresponds to the formula Ba3Me2Fe24O41, wherein Me stands for one or more divalent ions selected from the group formed by Co, Fe, Mn, Ni, Zn, Mg and (Li.Fe)1/2. Even at very high frequencies, these materials exhibit a small loss factor. The mouldings in accordance with the invention are extremely suitable for use in antennas.
    • 本发明涉及六方晶系烧结烧结体的成型。 该成型的特征在于,该材料的大部分晶粒具有单畴结构。 因此,如果所述材料在100MHz或更高的频率范围内使用,则该材料的损耗因子tanδ远小于相应的已知材料的损耗因子tanδ。 获得该材料的单畴结构,特别是如果材料的平均晶粒尺寸小于2.8微米。 平均粒径优选在1.4微米和2.5微米之间。 特别优选组成对应于式Ba3Me2Fe24O41的那些铁氧体材料,其中Me表示选自Co,Fe,Mn,Ni,Zn,Mg和(Li.Fe)中的一种或多种二价离子 )1/2。 即使在非常高的频率下,这些材料表现出小的损耗因子。 根据本发明的模制品非常适合用于天线。
