Controlling precipitation processes in the production of value-added zirconia. Doral Specialty Chemicals produces specialised zirconia products from zircon sands mined in WA. Doping the zirconia with metals such as yttrium and aluminium can produce advanced ceramics, with applications in areas such as solid oxide fuel cells and oxygen sensors.

Doral Specialty Chemicals produces specialised zirconia products from zircon sands mined in WA. Doping the zirconia with metals such as yttrium and aluminium can produce advanced ceramics, with applications in areas such as solid oxide fuel cells and oxygen sensors. The aim of this project is to improve the fundamental understanding of the chemistry in the initial processing steps, so that the process can be readily modified to produce new doped zirconia ceramics, without the extensive empirical process development currently required. The resulting ability to quickly produce new compositions on a commercial scale will put this industry in a world-leading position, dramatically increasing the added value of the zirconia products.Read moreRead less
Structural studies of titanyl and zirconyl sulfate hydrates. This project aims to provide knowledge that will inform the development of new methods of extraction and refining of titanium from ilmenite ores. In addition the knowledge gained in this research will aid the design and synthesis advanced ceramics and nanocomposites, and will provide the fundamental understanding of material structures that are required to adequately control the formation of such materials.
Enzyme-Mediated Machining of Chelators to Bind and Recover Valuable Metals. Metals are critical components of electronic devices and electrical products. Rapid disposal cycles create a major problem in managing e-waste metals and identifies an opportunity in the circular economy for recovery and re-use. Organic compounds that bind metal ions (chelators) are useful but could be improved to select a target metal from a mixture. This project aims to dissect a method used by bacteria to biosynthesiz ....Enzyme-Mediated Machining of Chelators to Bind and Recover Valuable Metals. Metals are critical components of electronic devices and electrical products. Rapid disposal cycles create a major problem in managing e-waste metals and identifies an opportunity in the circular economy for recovery and re-use. Organic compounds that bind metal ions (chelators) are useful but could be improved to select a target metal from a mixture. This project aims to dissect a method used by bacteria to biosynthesize chelators and hijack this to bioengineer new classes of chelators. Outcomes include new chelators and advanced knowledge of metal selectivity, with potential environmental and economic benefits arising from recovery of valuable metals. The project will benefit chemical biology research training for real-world applications.Read moreRead less
