The primary results of investigations of the surface tension (ST) of indium for the last six decades are considered in this review, and original data on the temperature dependence of the ST of indium obtained by authors using the sessile large drop and maximal drop pressure methods are given. Primary attention is paid to analyzing the possible methodological drawbacks of experimental studies, in which surface tension values of pure indium and some other metals, significantly exceeding the ST data, determined by traditional classic meth ods, are obtained. In the authors' opinion, the cleaning of the studied metal surfaces by heavy ion bombard ments of inert gases, which is used in similar works, cannot guarantee obtaining true surface tension values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
