Abstract

A description is given of three similar but structurally different experiments to study the diffusion of lead in molten tin at temperatures above the melting point of lead. Their comparative results cannot be explained within the generally accepted paradigm of the liquid state and indicate the existence of an additional mechanism of mass transfer in a melt to normal diffusion that is completely different from the generally accepted models. It is shown that the mass transfer components in a metal melt are largely determined by the area of the lyophobic surface in contact with the liquid metal, confirming earlier assumptions that there is an interfacial layer at the boundary between a melt and a capillary wall, and the component atoms flowing in this layer are in the state of bosons.
