High Purity Alumina or HPA is a specialty product of at least 99.99% pure Al2O3. It is a bad conductor of electricity and has a very high melting point. HPA finds its application in LED lighting, semiconductors, lithium-ion battery separators, scratchproof artificial sapphire glass, fingerprint readers and many more. Demand for high purity alumina stood at nearly 25,315tpa in 2016. During the period of 2016-2024, global HPA market is forecast to exhibit a CAGR of 16.7%, on account of rapid adoption of HPA in these applications.
High purity alumina (HPA) is emerging as the major material used in lithium-ion batteries, backed to its features. HPA is expected to the next major battery metal. Some of HPA benefits in lithium-ion batteries are as follows:
- HPA is a bad conductor of heat. Since lithium-ion batteries generate a lot of heat, they can catch fire. However, HPA use makes them safe.
- Separators coated with HPA boosts the thermal stability and efficiency of the batteries. According to some sources, high purity alumina of 38,000tpa would be needed for coating the separators in lithium-ion batteries by 2025.
- HPA also enhances battery life cycle and reduces self-discharge.
Several companies are getting engaged in the business of HPA, banking on growing demand for the material in the coming years. Some of the major stocks listed on ASX that are dealing in the HPA market are:
- Altech Chemicals Ltd (ASX:ATC)
- Pure Alumina Limited (ASX: PUA)
- FYI Resources Limited (ASX:FYI)
- Platina Resources Limited (ASX:PGM)
- Nova Minerals Limited (ASX:NVA)
Let us have a look at recent updates from three of these ASX-listed stocks and see how their stocks are performing.

The company has mobilised drill crew and rig on the first spotted hole location and is set to start drilling program in the next few days. After the completion of IP and Magnetic geophysical surveys, the company will start surface sampling and geologic mapping program at RPM and Shoeshine prospects in early July 2019.
Pacific Rim Geological Consulting of Fairbanks Alaska carried out the 2018 mapping campaign at the project of Estelle Oxide. The campaign demonstrated that higher gold values are related to bismuth telluride and arsenopyrite mineral phases. The campaign also highlighted that sheeted quartz veins containing narrow alteration selvages hosts the mineralogy.

The project area of Estelle covers several alterations zones and structures, in addition to identified mineral occurrences within a huge tenure. The IP survey will focus the drilling down to the key areas that would result in tonnes for the companyâs maiden Inferred Resource, said NVA Managing Director, Avi Kimelman.
