Indium Corp and Ames National Lab team to establish US gallium supply chain
Indium Corp of Clinton, NY, USA (a supplier of refined gallium, germanium, indium and other specialty technology metals) and Ames National Laboratory have announced an R&D partnership to expand US production of gallium. The new alliance will focus on developing the technologies needed to establish a domestic supply chain for an element that currently relies almost exclusively on imported sources.
“This collaboration brings together the teams’ advanced research capabilities and deep materials expertise to address a critical gap in the US supply chain,” says Indium Corp’s president & CEO Ross Berntson. “By focusing on scalable, data-driven solutions, we’re confident our work will enable more reliable gallium access for the industries that depend on it — and position Indium Corporation at the forefront of a domestic supply chain that is increasingly vital to US semiconductor and electronics manufacturing,” he adds.
“There is currently no domestic gallium production and no complete US gallium supply chain,” notes Ames Lab scientist and project leader Long Qi, an expert in chemical separations and catalysis. “The partnership goal is to change that, and the effort aligns well with the Department of Energy’s mission to develop critical materials production here.”
In the USA, gallium is recovered as a byproduct of well-established, high-volume aluminium refining operations. The Bayer process uses caustic liquids and high temperatures to extract and refine aluminium from raw ore. Gallium is typically present in the refining process waste in low concentrations of about 100 parts per million.
“Despite the low concentrations, we see an opportunity to develop a process that efficiently separates and extracts gallium as an additional high-value material from aluminium production,” Berntson says. “Indium Corporation’s experience as a materials refiner and smelter, and Ames Labs’ specialized techniques are the perfect union to make this happen.”
Liquid-based refining methods typically use specialized polymer resins that can separate and concentrate metals from mining solutions. For this project, Ames Lab researchers are designing a heat-stable, efficient resin that is selective for gallium.
Ames Lab’s robotic lab capabilities can carry out a large number of experiments and generate high-quality data quickly. When paired with AI tools, the data can be rapidly analyzed to uncover patterns, optimize processes, and guide the iterative design of materials. These accelerated workflows can shrink the development timeline from decades to as little as two to three years.
“By using our automated chemistry capabilities and AI tools, we can generate over 100 data points daily for our AI model,” Qi says. “This dramatically accelerates our timeline for developing a solution that surpasses current industry-leading materials.”
Scaling the technology is a joint effort, which will be done through a Cooperative Research and Development Agreement (CRADA): Indium Corp will provide a US resin testbed that mirrors high-volume production and techno-economic models to define the required material properties, and Ames Lab will synthesize materials up to the hundreds-of-grams scale. Future scale-up to kilograms and tons will continue collaboratively.
“This work is an important step toward unlocking new value from existing industrial processes,” believes Robert Ploessl, Indium Corp’s product manager for Metals and Compounds, and CRADA lead for the company. “By combining innovative materials development with practical scale-up pathways, we’re helping lay the groundwork for more resilient and sustainable sourcing of gallium and other critical elements.”
