Nanocrystalline metals are very promising materials both in form of nanoparticles and also as bulk materials. The production of such materials is usually limited by small amount of prepared metals and alloys. One of the possible ways of industrial production is selective leaching. This technique lays in preparation of supersaturated solid solution of desired element in matrix metal – by convenient heat treatment or by rapid solidification of the binary alloy. Consequently, the matrix metal is selectively dissolved and metal nanoparticles from other metal are formed. The size, shape and agglomeration of forming metallic nanoparticles are dependent on many factors such as reaction temperature, concentration of leaching solution, additives present in leaching solution. In our research we use mainly aluminium matrix. The reason for this is amphoteric behaviour, which enables aluminium dissolution in sodium hydroxide without affecting the minor metal.
