The School of Chemical Engineering at the University of Queensland worked in collaboration with Abercorn Kaolin Pty Ltd (since late 2018), a wholly owned subsidiary of Zeotech to develop a novel approach to HPA production.
Zeotech owns 100% of the Intellectual Property associated with the provisional patent application and as announced to the ASX on 17th October 2019, kaolin from Zeotech’s Abercorn Project has successfully produced 4N HPA (99.99%+) Al2O3 using a traditional process.
HPA demand increasing
The HPA market is experiencing significant growth. Demand is primarily being driven by sapphire glass and lithium-ion batteries. HPA is a very pure form of aluminium oxide (Al2O3) and a pre-cursor material required for the manufacturing of sapphire glass and ceramic coated Lithium-Ion-Battery separators.
HPA is a critical input in the production of synthetic sapphire – one which has no substitute. Applications:
- Substrates for LED lights, Lenses and Semiconductors
- Scratch-resistant sapphire glass used for optical lenses, watch faces, televisions, tablet and smartphone components
- Bio-medical devices and Phosphors
The higher brightness, energy efficiency, and longer life span of LED lights are some of the major factors that offer tremendous opportunities for LED lighting market in years to come.
