The nano- powder which is produced by the production method and this method of the high purity metal nano- powder

摘要

This invention discloses the new production method of the metal nano- powder. Until this low simple process although the metal nano- powder which includes the first metal is produced on an actual scale is specialized at cost, in order the step which forms the alloy which difference the first metal or the metal and from the first metal or the metal includes one second solubility metal, at least, to become the homogeneous alloy, in order to become step and the thin layer which administer first heat treatment, can obtain the phase constitution of step and the specified feature which administer cold working to the homogeneous alloy, the step which administers second heat treatment to the alloyWith, at least one solubility metal, it exposes the alloy vis-a-vis the exudation medicine which has reached the point where it exudes effectively and step and, the step which deviation from makes step and make the powder dry step and the step which covers the powder with the reagents and was covered the powder convert which it filters and washes the powder which is obtained and massively and, having it becomes. In addition as for this invention, low and also the metal nano- powder of high purity is disclosed at the cost which is produced with the above-mentioned method.
