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.

大多数化学反应发生在表面或界面。 流体扩散或覆盖表面的接触面积和容易程度主要取决于流体的表面张力或表面能。 在金属和先进陶瓷材料的加工过程中，熔融氧化物的行为可以极大地影响反应速率、相之间的界面质量，从而影响所生产的先进材料的机械和其他关键性能。 该项目提供了一种预测熔融氧化物表面张力的方法，使设计，控制和改进金属和材料制造工艺成为可能。
