Title (EN) ALUMINUM PARTICLE GROUP AND METHOD FOR PRODUCING SAME
(FR) GROUPE DE PARTICULES D'ALUMINIUM ET SON PROCÉDÉ DE PRODUCTION
(JA) アルミニウム粒子群およびその製造方法
Abstract:
(EN) An aluminum particle group which is composed of aluminum particles and is configured such that, in an observation image of the aluminum particle group as observed with a scanning electron microscope: the average circularity of the aluminum particle group is 0.75 or more; the average particle diameter D50 of the aluminum particle group is 10 μm or more but less than 100 μm; and if A is the number of aluminum particles having a diameter of less than 5 μm, B is the number of aluminum particles having a diameter of 10 μm or more, C is the number of aluminum particles having no satellite, and D is the number of aluminum particles having a satellite, A, B, C and D satisfy A × 3 ≤ B and D < C.
(FR) L'invention concerne un groupe de particules d'aluminium qui est composé de particules d'aluminium et qui est conçu de telle sorte que, dans une image d'observation du groupe de particules d'aluminium comme observé à l'aide d'un microscope électronique à balayage : la circularité moyenne du groupe de particules d'aluminium est égale ou supérieure à 0,75 ; le diamètre moyen de particule D50 du groupe de particules d'aluminium est égal ou supérieur à 10 µm, mais inférieur à 100 µm ; et si A est le nombre de particules d'aluminium présentant un diamètre inférieur à 5 µm, B est le nombre de particules d'aluminium présentant un diamètre égal ou supérieur à 10 µm, C est le nombre de particules d'aluminium n'ayant pas de satellite et D est le nombre de particules d'aluminium ayant un satellite, A, B, C et D sont tels que A × 3 ≤ B et D < C.
(JA) アルミニウム粒子からなるアルミニウム粒子群であって、走査型電子顕微鏡を用いてアルミニウム粒子群を観察したときの観察画像において、アルミニウム粒子群の平均円形度は0.75以上であり、アルミニウム粒子群の平均粒径D50は、10μm以上100μm未満であり、直径が5μm未満のアルミニウム粒子の数をAとし、直径が10μm以上のアルミニウム粒子の数をBとし、サテライトを有さないアルミニウム粒子の数をCとし、サテライトを有するアルミニウム粒子の数をDとしたとき、A×3≦Bを満たすとともに、D<Cを満たす。
