FERRITE SINTERED MAGNET, FERRITE GRAINS, BONDED MAGNET, AND ROTATING ELECTRICAL MACHINE
The magnet is a ferrite sintered magnet which has a ferrite phase having a magnetoplumbite-type crystal structure, and contains at least a metal element A, a metal element R, Fe, Co, Zn and B. The metal element A comprises at least one element selected from the group consisting of Sr, Ba, Ca and Pb, and essentially contains Ca. The metal element R comprises at least one element selected from the group consisting of rare earth elements including Y and Bi, and essentially contains La. The atomic ratio between the metal elements satisfies the following formulae: A1-rRrFexCoyZnz (1); 0.40 <= r <= 0.70 (2); 8.20 <= x <= 9.34 (3); 0.05 < y <= 0.50 (4); and 0 < z <= 0.20 (5). Furthermore, the content of Si is 0 to 0.60% by mass in terms of the content of SiO2, and the content of B is 0.01 to 0.70% by mass in terms of the content of B2O3.
该磁体是含有具有磁铅石型的结晶结构的铁氧体相的铁氧体烧结磁体，至少含有金属元素A、金属元素R、Fe、Co、Zn及B。金属元素A是选自Sr、Ba、Ca和Pb中的至少一种元素，必须含有Ca。金属元素R是选自含有Y的稀土元素及Bi中的至少一种元素，必须含有La。金属元素的原子比率满足下式。A1－rRrFexCoyZnz(1)，0.40≤r≤0.70(2)，8.20≤x≤9.34(3)，0.05＜y≤0.50(4)，0＜z≤0.20(5)，另外，Si的含量以SiO2换算计为0～0.60质量％，B的含量以B2O3换算计为0.01～0.70质量％。
