It is significant to understand deeply interfacial properties and interfacial phenomena appeared in high temperature metallurgical processing. In particular, highly purified steel production is a clear and important goal to be aimed at in steelmaking processes. In order to produce highly purified steel, there are a lot of subjects which we should cope with, such as generation and growth of nonmetallic inclusions and their wettability with liquid steel, and furthermore engulfing small droplets of molten slag or CC molten flux into liquid steel. Those subjects are strongly related to interfacial properties and interfacial phenomena of liquid steel, solid oxides, and molten slag. In addition, solidification of metals and alloys are also related to interfacial phenomena between solid and liquid phases.In this chapter, we focus on (1) wettability between liquid metals and solid oxide, (2) interfacial free energy between solid and liquid phases in metals and alloys, and (3) interfacial tension between liquid steel and molten slag and some fundamental information on them are explained.
