Temperature coefficient of surface tension for pure liquid metals

Abstract The temperature coefficient of surface tension σ ′ of pure metals is calculated on the basis of Skapski's nearest-neighbour interaction-broken-bond model, modified in order to take into account the effect of thermal expansion of liquid surfaces. Calculated values of σ ′ are compared with experimental results for 19 metals for which σ ′ is known with a good accuracy. Finally, the value of σ ′ is given for 45 other metals for which this quantity is not well known or even has never been measured.
