Nathan Webster


Australia

Dr Nathan Webster joined CSIRO Mineral Resources in 2008, after obtaining a PhD in solid-state chemistry from the University of Western Australia. He now leads the Diffraction Laboratory within CSIRO Mineral Resources in Clayton, VIC, a laboratory which specialises in in-situ diffraction analyses of metallurgical systems and materials-forming reactions. In particular, Nathan has built up a significant body of work in the field of iron ore sintering research. Nathan is the current President of the Australian X-ray Analytical Association (AXAA), and is CSIRO’s Councillor on the Australian Institute of Nuclear Science and Engineering (AINSE) Council.


Session: In Situ Analysis

The ability to “see” into a dynamic process, whether it be a mineral formation or minerals processing reaction, is hampered when a specimen is removed from its environment for analysis. When a specimen is cooled, removed from highly reducing conditions or removed from high pressure, for example, its characteristics will change and this affects a post-mortem or ex situ analysis. The utility of X-ray and neutron methods, in particular, to be applied in situ and where process conditions are simulated in the laboratory or at a synchrotron or neutron beamline, has enabled deep insights into mineral formation mechanisms and kinetics in a wide range of applications. This session would highlight many of these as well as discuss the start-of-the-art in the field, future directions and opportunities.
