N2 - High energy X-ray diffraction (HEXRD) combined with containerless levitation techniques have proved, over the past decade or so, to be an excellent method of determining the structure of refractory liquids. A successful programme of the study on stable liquids has been undertaken at the Advanced Photon Source (APS) using these combined techniques. Systems studied so far include Al2O3-SiO2, Al2O3-Y2O3, SiO2-CaO and SiO2-MgO. Fast image acquisition techniques have also been developed and complete diffraction patterns can now be acquired in as little as 200ms. It is therefore possible to explore the structure deeply supercooled liquids where the viscosity changes most dramatically. A recent development has been to control the composition of levitation gas adding a further dimension (pO2) to phase space. This means that liquids containing iron and other transition metals, which are of interest to the ceramic, materials and Earth science communities, can now be studied.
