Surface Properties of Liquid Alloys & Molten Slag
Surface property of liquid alloys and molten ionic mixtures such as molten slag is one of the important physico-chemical properties directly related to various surface phenomena in metallurgical processing. Although there have been so far a lot of information on the surface properties of alloys and oxides etc., a prediction of physico-chemical properties are quite important to design a new materials processing. The authors have tried to develop a system to predict various physico-chemical properties such as surface tension and viscosity on the basis of thermodynamic databases, which are usually used to calculate phase equilibria, chemical reactions and so on. The simultaneous evaluation of those various properties is quite significant to investigate complicated phenomena at high temperature material processing. We have already derived various models to predict surface properties of liquid alloys and molten ionic mixtures, such as surface tension of liquid metals and alloys, the effect of oxygen on surface tension of liquid metals, surface tension of molten ionic mixtures and interfacial tension between liquid steel and molten slag, the effect of particle size on nano-sized alloy phase diagrams. In the present paper, we summarize our trials to evaluate various surface properties of alloys and slag etc., and mainly describe our recent models to predict the surface tension of molten slag.
