It is considered proofs of a size quantization (linear and bulk) in processes of phase transformations from polymorphic to a boiling at high temperature. It is shown that atomic space between atomic and ionic radii is divided into the ready Kλ cells (where K - nearest neighbors, λ = h/mc), that is - the atomic coordination space is discrete for the placing Kλ. It is shown also, that cell- Kλ is the result of exchange interaction photon + electron →λ between emitter and absorber of photons. The model ± Kλ may be employed both the nontransition metals and transition and also its has been employed into the analysis of the formed of the amorphous structure by the freezing of the liquid metals. It is shown also particularity of the model Kλ for noble metals and the formation of the hexagonal structure and also phase transformations: ordinary crystallization and bcc - fcc and also bcc – hcp. It is considered processes the melting, the boiling and the formed of clusters.
