The temperature coefficient of surface tension ? 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 ? are compared with experimental results for 19 metals for which ? is known with a good accuracy. Finally, the value of ? is given for 45 other metals for which this quantity is not well known or even has never been measured.

Abstract
The temperature coefficient of surface tension ? 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 ? are compared with experimental results for 19 metals for which ? is known with a good accuracy. Finally, the value of ? is given for 45 other metals for which this quantity is not well known or even has never been measured.File in questo prodotto:
