5N Plus’ $18.1M U.S. for Germanium for IR Optics and Space Solar

On January 30, 2026, 5N Plus announced it had received an US$18.1 million grant from the U.S. government to expand germanium recycling and refining operations at its St. George, Utah facility, to increase supply of high-purity germanium into optics and solar germanium crystal supply chains that underpin infrared optics and power systems used in satellites and other high-reliability platforms.

The funding forms part of a broader federal effort under recent U.S. executive directives aimed at increasing domestic critical-mineral production and reducing exposure to concentrated foreign supply.

“This award reinforces our unique leadership position as a trusted partner with the sourcing, refining, and manufacturing expertise to supply high-purity specialty semiconductors to key customers for mission-critical applications,” said 5N Plus President and CEO Gervais Jacques. “We are proud that our St. George, Utah facility has once again been recognized as a key partner to the U.S. government.”

What Exactly is Being Expanded?

The funding supports an expansion of domestic germanium recycling and refining capability, allowing more of the recovery, purification, and qualification work to happen inside the U.S. Rather than relying primarily on imported finished material, this approach emphasizes process control, traceability, and repeatability that are especially critical for defense, aerospace, and space-qualified applications.

Just as important is feedstock flexibility. 5N Plus has signaled that the expanded operation will increase recovery from industrial residues and mining by-products, not just primary sources. This widens the usable input pool and reduces exposure to single-source or policy-constrained supply, aligning with the broader push toward circular and resilient critical-materials supply chains.

The company’s projected 48-month scale-up window is also telling. Upstream specialty materials do not come online overnight; new equipment must be installed, processes stabilized, and output qualified before capacity becomes usable. In high-purity germanium, consistency and yield often constrain supply as much as nominal production volume.

Ultimately, the expansion is expected to enable up to roughly 20 metric tons per year of high-purity germanium, supplementing 5N Plus’ existing sourcing and refining footprint. In absolute terms this is a small number but in space, defense, and optics markets, where demand is measured in tons and substitution options are limited, it represents meaningful incremental capacity.

Germanium is one of those materials that rarely attracts attention until supply tightens and can quickly become a program-level risk.

5N Plus supplies high-purity, space-qualified germanium wafers used across infrared optics, EO/IR surveillance systems, and satellite solar cells, as well as in certain fiber-optic, semiconductor, and specialty electronics applications. These uses sit deep inside systems where redesign is costly and requalification can take years.

In defense and aerospace, germanium is foundational to thermal imaging, missile warning, and ISR platforms, where uninterrupted material availability directly affects production schedules and deployment timelines. In space systems, germanium substrates remain critical for high-efficiency, radiation-resistant solar cells, making supply stability a prerequisite for satellite launches rather than a downstream consideration.

Industrial and medical imaging markets tend to consume smaller volumes, but they are not insulated. When germanium supply tightens, allocation often shifts toward national-priority programs first, leaving indirect users exposed to longer lead times and reduced availability.

Germanium behaves less like a commodity and more like an enabling constraint. Its impact is felt not just in pricing, but in lead times, qualification cycles, and the ability to execute on long-term programs.

Why the U.S. is Funding refining now?

The move comes amid heightened awareness of critical minerals as strategic economic and national security assets.

China’s dominance in the global production and export of critical minerals has sparked concern across industrial and policy circles: export licensing requirements introduced in 2023 for gallium and germanium, for example, saw Chinese exports of these materials plummet and added friction to global supply chains.

A U.S. Geological Survey study found that strict export bans or disruptions in germanium and gallium supply could cost the U.S. economy billions in GDP highlighting the tangible risk of concentrated supply sources.

In policy terms, this has shifted strategy from simple trade liberalization toward supply-chain diversification and domestic capacity building not just for rare earths and lithium, but for materials like germanium that appear deep in the value chain.
