Specific features of the evolution of electrolytic copper microcrystals with inhibition of the growth of low-energy facets

Experimental evidence for the possibility of controllably transforming the habit of copper microcrystals formed by electrodeposition has been presented. Selective evolution of microcrystal facets with a specific crystallographic orientation has been performed by a premeditated change in the chemical composition of a standard sulfuric electrolyte. The experiments have proved the existence of a small particle with icosidodecahedral morphology as an intermediate stage of the evolution of the small particle from an icosahedron to a dodecahedron and demonstrated some elastic-energy relaxation channels associated with inhibition of the growth of low-energy facets of electrolytic copper microcrystals.
