Abstract:
(EN) Mn-Zn ferrite particles according to the present invention contain 44-60% by mass of Fe, 10-16% by mass of Mn and 1-11% by mass of Zn. The ferrite particles are single crystal bodies having an average particle diameter of 1-2,000 nm, and have polyhedral particle shapes, while having an average sphericity of 0.85 or more but less than 0.95.
(FR) Les particules de ferrite Mn-Zn selon la présente invention contiennent de 44 à 60 % en masse de Fe, de 10 à 16 % en masse de Mn et de 1 à 11 % en masse de Zn. Les particules de ferrite sont des corps monocristallins ayant un diamètre moyen de particule de 1 à 2000 nm, et ont des formes de particules polyédriques, tout en ayant une sphéricité moyenne de 0,85 ou plus mais inférieure à 0,95.
(JA) 本発明のMn-Zn系フェライト粒子は、Feを44~60質量%、Mnを10~16質量%、Znを1~11質量%含有するMn-Zn系フェライト粒子であって、当該フェライト粒子は、平均粒径が1~2000nmの単結晶体であり、且つ、平均球形度が0.85以上0.95未満であって多面体状の粒子形状を備える。
