Abstract: front page image
(EN)A soft magnetic material, and dust magnetic core, not only capable of preventing iron loss deterioration but also excelling in deflecting strength. There is provided a soft magnetic material comprising multiple composite magnetic particles (30) each having metal magnetic particle (10) and, surrounding the surface thereof, insulating coating (20). The metal magnetic particle (10) is composed mainly of iron. The insulating coating (20) contains aluminum, silicon, phosphorus and oxygen. When, contained in the insulating coating (20), the molar amount of aluminum is referred to as MAl, the sum of molar amount of aluminum and molar amount of silicon as (MAl+MSi) and the molar amount of phosphorus as MP, there are simultaneously satisfied the relationships 0.4≤MAl/(MAl+MSi)≤0.9 and 0.25≤(MAl+MSi)/MP≤1.0.
(FR)La présente invention concerne un matériau magnétique doux et un noyau magnétique à poudre de fer qui sont non seulement capables d’empêcher la détérioration de la perte de fer, mais qui présentent également une excellente résistance à la déviation. Le matériau magnétique doux comprend de multiples particules magnétiques composites (30) possédant chacune une particule magnétique métallique (10) et un revêtement isolant (20) enveloppant sa surface. La particule magnétique métallique (10) se compose principalement de fer. Le revêtement isolant (20) contient de l’aluminium, du silicium, du phosphore et de l’oxygène. Lorsque, une fois présente dans le revêtement isolant (20), la quantité molaire en aluminium correspond à MAl, la somme de la quantité molaire en aluminium et de la quantité molaire en silicium correspondent à (MAl+MSi) et la quantité molaire en phosphore correspondent à MP, les relations sont satisfaites simultanément 0,4≤MAl/(MAl+MSi)≤0,9 et 0,25≤(MAl+MSi)/MP≤1,0.
(JA) 鉄損の悪化を防止するとともに、抗折強度の優れた軟磁性材料および圧粉磁心を提供する。軟磁性材料は、金属磁性粒子(10)と、金属磁性粒子(10)の表面を取り囲む絶縁被膜(20)とを有する複数の複合磁性粒子(30)を備えている。金属磁性粒子(10)は、鉄を主成分とする。絶縁被膜(20)は、アルミニウム、シリコン、リン、および酸素を含む。また、絶縁被膜20に含有されているアルミニウムのモル量をMAlとし、アルミニウムのモル量とシリコンのモル量との和を(MAl+MSi)とし、リンのモル量をMpとした場合に、0.4≦MAl/(MAl+MSi)≦0.9の関係と、0.25≦(MAl+MSi)/Mp≦1.0の関係とを満たす。
