The Physicochemical Properties of Complex Silicate Melts - Application of a New Quasichemical Model to Surface Tension Prediction

点击翻译按钮获取中文摘要

Most chemical reactions occur at surfaces or interfaces. The contact area and ease in which fluids spread or cover surfaces depends critically on the surface tension or surface energy of the fluid. In the processing of metals and advanced ceramic materials the behaviour of molten oxides can greatly influence the rates of reactions, the quality of the interfaces between phases and therefore mechanical and other key properties of advanced materials produced. This project provides a means of predicting the surface tensions of molten oxides, making it possible to design, control and improve metal and material manufacturing processes.
