Lava Blue is a science-led, unlisted public company, developing a High Purity Alumina project on granted mining and exploration permits in north Queensland.

While mining sapphire from its gemfields in north Queensland and exploring for other minerals, Lava Blue discovered that the clays that host the gem quality sapphire also contain up to 30% Al2O3.

High purity alumina is >99.99% pure Al2O3, also known as 4N HPA, and is a chemically inert ceramic material with high thermal and electrical resistivity. These properties have made HPA the basis for all LEDs and sapphire glass. It is also highly effective in electronic displays and in semiconductors.

In addition, HPA Is now a critical material for making ceramic coated separators that are critical to the safety and performance for both lithium and aluminium batteries.

​

Lava Blue is now perfecting the process of manufacturing 4N HPA from the extensive resources it controls.
