Abstract: Selective leaching is process used mainly in analytical praxis–alloy matrix is dissolved and the residuum can be study by different methods. In this article, modification of selective leaching determined for production of metallic nanoparticles is described.Selective leaching 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. The metal mainly used as matrix component is aluminium due to is amphoteric behaviour. It enables aluminium dissolution in sodium hydroxide without affecting the minor metal. Nobel metals like silver or copper forms
Keywords: Nanocrystaline materials; selective leaching
