Complex multi-component molten oxide phases, known commonly as slags, are used in the high temperature production and refining of metals. The slag systems of commercial interest contain transition metals species, such as, Fe2+, Fe3+. Each of these species behaves as if it were a separate chemical component. Researchers at the University of Queensland have developed a new methodolgy, which enables the concentrations of these transition metal ions to be measured. These types of measurements cannot be made with any of the techniques currently in use. The study will provide data on high temperature slags in a number of industrially and scientifically important systems. This approach will be applicable to a wide range of chemical systems in the fields of extractive metallurgy, materials science and geology; systems which could not previously be characterised.

复杂的多组分熔融氧化物相，通常称为炉渣，用于高温生产和金属精炼。 具有商业意义的炉渣体系含有过渡金属物质，例如Fe 2+、Fe 3+。这些物质中的每一种都表现得好像它是一种单独的化学成分。昆士兰州大学的研究人员开发了一种新的方法，可以测量这些过渡金属离子的浓度。 这些类型的测量不能用目前使用的任何技术进行。这项研究将提供一些工业和科学上重要系统中高温炉渣的数据。这种方法将适用于提取冶金、材料科学和地质学领域的各种化学系统;这些系统以前无法表征。
