Abstract [en]

In view of the importance of generating reliable and self consistent thermophysical data, efforts have been made in the Division of Metallurgy, Royal Institute of Technology, Stockholm to measure the viscosities and thermal diffusivities of multicomponent slags as well as surface- and interfacial tensions. The measurements were also carried out in the dynamic mode to monitor high temperature reactions and understand the underlying mechanisms. In the latter case, the rate of dissolution of alumina in a slag as well as the rate of oxidation of Fe2+ in a fayalite slag were followed by measuring the viscosities along the reaction coordinate. The reaction rate between liquid iron with different oxygen levels and alumina/silica substrates was studied by the sessile-drop method. The paper illustrates the usefulness of this approach in understanding high temperature phenomena.
