【Ferro-alloys.com】：Hazer Group has announced that independent testing has confirmed its graphite can be upgraded to more than 99.99% purity using thermal purification, marking a step forward in the company’s efforts to develop higher-value applications for its graphite co-product.

According to Hazer, the testing was conducted by ANZAPLAN, a division of the Dorfner Group that specialises in battery-grade graphite and specialty minerals technology.

The third-party assessment found that Hazer Graphite can be thermally purified to exceed 99.99% purity by weight, enabling further evaluation for battery-related applications, including conductive agents and battery anodes for lithium-ion and potentially sodium-ion batteries.

The company said it and ANZAPLAN plan to undertake electrochemical validation testing during the second half of 2026 to assess the material’s electrical performance.

Hazer CEO and managing director Glenn Corrie said the result represented a significant milestone in the company’s graphite development strategy.

“Developing high end applications for Hazer graphite has been a goal of Hazer for years and engaging the Dorfner Group has significantly increased our probability that the battery market will open up for our material,” Corrie said.

“Completing the upgrading of Hazer graphite to this level is a major milestone in the development of an internationally available high-quality graphite for critical applications.”

Corrie added that the company was continuing to pursue commercial opportunities for its graphite in concrete, asphalt, steelmaking and water treatment, alongside battery materials.

Hazer said the latest results complement its previously announced proprietary low-energy graphite purification method, which was patented in 2025.

The company stated that having both its own purification technology and conventional thermal purification available provides multiple pathways for upgrading graphite for higher-value applications.

The company said battery-grade processing could broaden the potential uses of its graphite co-product and strengthen the commercial prospects of its dual-product business model.

It also noted that earlier this year, Hazer Graphite was qualified by Boral MTS as an additive for improving the performance of structural concrete and asphalt, while continuing to be evaluated for use in lower-emissions steelmaking.

According to Hazer, most graphite produced from future Hazer facilities is expected to be supplied into high-volume applications such as asphalt, concrete and steelmaking.

However, the company said it also intends to pursue higher-value niche markets that require additional processing, with the aim of expanding market opportunities and supporting the commercialisation of graphite produced by future Hazer technology licensees.
