TEMPERATURE-COEFFICIENT OF SURFACE-TENSION FOR PURE LIQUID-METALS

The temperature coefficient of surface tension sigma' of pure metals i s calculated on the basis of Skapski's nearest-neighbour interaction-b roken-bond model, modified in order to take into account the effect of thermal expansion of liquid surfaces. Calculated values of sigma' are compared with experimental results for 19 metals for which sigma' is known with a good accuracy. Finally, the value of sigma' is given for 45 other metals for which this quantity is not well known or even has never been measured. (C) 1998 Elsevier Science B.V. All rights reserve d.
