Review of surface tension data for metallic elements and alloys: Part 1 - Pure metals

There have been a large number of papers on the surface tensions of metals since Keene published his critical review in 1993. Consequently, current data for both the surface tensions of metals and their temperature dependencies have been critically assessed and recommended values are given. Experimental uncertainties can arise from two sources: systematic errors associated with the experimental methods (typically +/-2%) and changes in surface tension arising from oxygen contamination of the specimen. Uncertainties arising from the latter can be variable.
