In order to understand the interfacial phenomena in metallurgical processes at high temperatures, surface and interface should be expressed energetically. In this chapter, surface tension and its temperature dependence are derived thermodynamically. When these surfaces meet each other, wetting phenomena may take place. The wetting can be described by the contact angle between the surfaces (or interfaces), which can be determined according to Young's equation or Smith's equation. In this chapter, three types of wetting are suggested briefly.
