Abstract:
(EN) Provided is a dust core which contains a powder of a crystalline magnetic material such as carbonyl iron, and which contains, as a dust core having excellent magnetic characteristics, a powder of a crystalline magnetic material and a powder of an amorphous magnetic material. This dust core is characterized in that a first mixing ratio, which is the mass ratio of the content of the powder of a crystalline magnetic material relative to the sum of the content of the powder of a crystalline magnetic material and the content of the powder of an amorphous magnetic material, is from 75% by mass to 95% by mass (inclusive).
(FR) L'invention concerne un noyau à poudre de fer qui contient une poudre d'un matériau magnétique cristallin tel qu'un fer de carbonyle, et qui contient, sous la forme d'un noyau à poudre de fer ayant d'excellentes caractéristiques magnétiques, une poudre d'un matériau magnétique cristallin et une poudre d'un matériau magnétique amorphe. Ce noyau à poudre de fer est caractérisé en ce qu'un premier rapport de mélange, qui est le rapport massique de la teneur de la poudre d'un matériau magnétique cristallin par rapport à la somme de la teneur de la poudre d'un matériau magnétique cristallin et de la teneur de la poudre d'un matériau magnétique amorphe, est de 75 % en masse à 95 % en masse (inclus).
(JA) カルボニル鉄のような結晶質磁性材料の粉末を含有する圧粉コアであって、優れた磁気特性を備える圧粉コアとして、結晶質磁性材料の粉末および非晶質磁性材料の粉末を含有する圧粉コアであって、前記結晶質磁性材料の粉末の含有量と前記非晶質磁性材料の粉末の含有量との総和に対する前記結晶質磁性材料の粉末の含有量の質量比率である第一混合比率が、75質量%以上95質量%以下であることを特徴とする圧粉コアが提供される。
