“…In case of the non-metallic inclusions a very high amount of iron and aluminum was registered, and the formation of FeAl 2 O 4 was identified with the aid of EDS analysis. Kapilashrami and Seetharaman [16] have found similar results (formation of a product layer based on FeAl 2 O 4 of approximately 80 mm between the alumina and the iron) by studying the wetting characteristics of oxygencontaining iron melts on alumina.…”

“…In the present work, p(O 2 ) is below this value, and the FeAl 2 O 4 cannot form. As found out by Kapilashrami and Seetharaman, [28] the critical oxygen partial pressure is 2EÀ10 bar for FeAl 2 O 4 formation. At 1600 8C the diffusivity of oxygen in liquid iron is %1.4EÀ4 cm 2 s À1 .…”

The effect of temperature, atmosphere, and elemental concentrations of boron and phosphorous in ferrous alloys on the wettability of polycrystalline α‐Al2O3 was studied. The investigation of the wetting behavior is of major importance to the infiltration of steel into open foam ceramics. In reference Fe‐0.46 wt% C iron samples, the contact angle was investigated between 1550 and 1650 °C under Ar‐H2 and Ar atmospheres and was found to decrease with increasing temperature and increasing oxygen partial pressure. Furthermore, no FeAl2O4 (hercynite) spinel type inclusions were found in Fe/Al2O3 experiments. In the Fe‐P binary alloys, θ decreased with increasing phosphorous content and was ≈112° for the Fe‐0.299 wt% P alloy at 1600 °C. For the Fe‐B binary alloys, a strong influence of boron on the contact angle was found. Secondary neutral mass spectrometry (SNMS) analysis showed a maximum in the boron concentration in the first 50 nm of the metallic side of the interface. In the FeCrMnNi‐P high‐alloys specimens, a reaction layer was found between the steel/ceramic interfaces. The contact angle was ca. 90°, lower than the Fe‐P binary alloys.

“…The IFT of the Fe alloy in contact with different slag systems has been studied using sessile drop and contact angle measurement by the following authors. ,,− In the last work, the dynamic interfacial phenomena during high-temperature reaction between an Fe−Al alloy droplet and a CaO−SiO 2 −Al 2 O 3 slag were analyzed by evaluating the thermocapillary, solutocapillary, and electrocapillary effects . Some other related references could be found in ref .…”

The present paper is an attempt to critically review the relevant techniques for the laboratory measurement of interfacial tension of high-temperature liquid−liquid systems, mostly linked with metallurgy and pyrochemistry. Even if the present paper is preferably devoted to interfacial high-temperature measurements, the same information concerning surface tension will be implicitly provided, as well. There will be no report of the techniques related to dynamic interfacial tension, measurements of ultralow interfacial tension, and the techniques used in microtensiometry and nanotensiometry. These methods (often call nonclassical techniques) are very hard to employ at high temperature, even if they could be in general used at these conditions.
