Influence of the adsorption of residual gas phase molecules in a measuring chamber on the surface tension of liquid metals

The surface tension of indium: Methods and results of investigations

“…Thus, the authors [120] bear in mind not the density value of the vapor phase as com pared with the liquid metal density, but the fact of its presence or absence. The statement of authors [120], made in their other work [107], namely, "The viola tion of equilibrium conditions in the system (different pressures and temperatures at different places of the system) little influences the surface tension value of the pure metal," convincingly testifies to that fact. In the authors' opinion, a similar statement is deeply erroneous.…”

“…The problem of the influence of gas adsorption on the fresh formed surface, taking place in the process of its aging, is considered in [107]. In the authors' opin ion [107], one of the main reasons for disagreement of the ST data for the same pure metals is the inevitable aging of the liquid metal drop surface, starting with the initial moment of its formation or the moment of its routine cleaning to renewal of measurements, as a result of which the ST value are changed.…”

One of basic arguments of the authors of works [54,71,92], in which increased values of the ST of some pure metals are obtained, is the reference to the ideal cleaning of the studied surface by electron and ion bombardments.…”
