For the first time, copper particles in the form of truncated micron-sized icosahedrons were experimentally obtained by electrodeposition, their morphology and internal structure were investigated. It is shown that fullerene-like copper microparticles grow from non-crystalline spherical nanoparticles and are transformed during electrocrystallization into perfect icosahedrons, which have a more stable shape and structure. The disclination models for the conversion of nanoparticles into icosahedral microparticles are developed and described.
