Compilations and data pertaining to the wettability and interfacial pr
operties of Fe-melts and dilute Fe-O-S alloys on alumina substrates ha
ve been collected and compared. The properties included the surface te
nsion of liquid Fe; the surface tension of Al2O3; measurements of work
of adhesion and contact angles; and the effects of sulfur and oxygen
on the surface tension of liquid Fe and on the contact angle. Based on
the comparisons, recommendations for estimating these interfacial pro
perties as well as the tension of the Fe-O-S (liquid)/Al2O3 interface
are given.
