Abstract

L'invention concerne une poudre d'étain qui présente une excellente stabilité de forme lorsqu'elle est traitée en une pâte d'étain et a également une excellente stabilité de liaison, l'invention concernant également une pâte d'étain et un procédé de fabrication de poudre d'étain. La poudre d'étain est caractérisée par le fait que la particule a une forme de flocon, et un diamètre équivalent à celui d'un cercle moyen dans la direction plane de la particule est de 1 μm-10 μm. La pâte d'étain utilise une telle poudre d'étain. Au moment de la fabrication de la poudre d'étain, la poudre d'étain ayant une forme de particules est dispersée dans un milieu de dispersion, et le coulis dispersé est traité dans un broyeur de milieu.
