Enhanced pigment weathering resistance by coating with high dielectric ceramic. The partner company, Tiwest, based in Western Australia, is a major contributor to the economy, and earns more than $A400m annually in exports. It is the only company in the world that mines, separates, refines and manufactures titania products, including pigments, in one region.

The partner company, Tiwest, based in Western Australia, is a major contributor to the economy, and earns more than $A400m annually in exports. It is the only company in the world that mines, separates, refines and manufactures titania products, including pigments, in one region. The current post-titania particle formation wet-coating process, however, presents a major capital and recurrent cost and necessitates a pigment regrind stage. The research will investigate the development of a highly durable dry-coated pigment utilising a novel high dielectric coating. This development has the potential to ensure the partner company's future competitiveness through reduced processing costs and improved product performance.Read moreRead less

The proposed research will enhance our ability to make both light emitting diodes (LEDs) and piezoelectric actuators from ZnO. LEDs are a high efficiency light source that save energy compared to conventional illumination sources and can be fabricated in thin films. The proposal is to also bring the technology for device fabrication to Australia where it can ultimately be used ....Controlling Anisotropic Growth of Metal Oxide Crystals in Aqueous Solution by Selective Adsorption of Small Molecules. The proposed research will enhance our ability to make both light emitting diodes (LEDs) and piezoelectric actuators from ZnO. LEDs are a high efficiency light source that save energy compared to conventional illumination sources and can be fabricated in thin films. The proposal is to also bring the technology for device fabrication to Australia where it can ultimately be used to broaden the economic base of the country. The knowledge of crystal growth rate and crystal morphology control can be applied to improvements in the efficiency of alumina production which is already an important contributor to Australian exports.Read moreRead less
Wet Particulate Materials - Flow or Fracture? Most advanced materials are produced from starting materials in the form of fine particles. Powders, especially in ceramic engineering, are first processed wet into near-final shape. Improved understanding of the fracture of particle networks is critical in order to process nano-sized advanced ceramic materials for use in solar energy harvesting and extreme heat engine applications as well as minimising drying cracks in paints and coatings.

Improved understanding of the fracture of particle networks is critical in order to process nano-sized advanced ceramic materials for use in solar energy harvesting and extreme heat engine applications as well as minimising drying cracks in paints and coatings. The research aims to identify the fundamental link between particle network strength and structure and the fracture of wet powder bodies. The microscopic mechanisms that control the behaviour will be investigated with a particular focus on toughening mechanisms including the influence of plasticity.Read moreRead less
A new paradigm in near-net-shape advanced ceramic component processing. The raw materials for high performance ceramics (such as alumina and zirconia) are readily available and produced in Australia. Nearly all of these raw materials are exported. The development of processing to make high value added ceramic components from these raw materials will result in greater profit and more jobs for Australians.
