Global Germanium Demand Soars as Buyers Seek New Supply and Alternatives

The U.S. Department of Defense (DoD)

With rising demand for germanium in defense and advanced computing, global consumers are seeking alternatives as China’s export restrictions have tightened supply. Germanium’s applications in artificial intelligence (AI) and autonomous vehicles have driven increased consumption, especially for its use in high-performance computing and infrared optics. AI systems benefit from silicon-germanium's ability to operate at higher frequencies and lower power, making it critical in modern technological advancements.

Germanium Supply Chain Concerns and Strategic Moves

The U.S. Department of Defense (DoD) is actively working to secure a sustainable germanium supply. The DoD has teamed up with LightPath Technologies to replace germanium in some of its applications, especially in optics, in a bid to reduce supply chain vulnerabilities. Meanwhile, other initiatives focus on increasing germanium consumption for defense purposes. The DoD is investing $14.4 million in 5N Plus, a Canadian semiconductor materials firm, to expand its capacity for producing germanium wafers for solar cells, ensuring continued supply for defense and satellite industries.

Producers are also responding to the supply crunch. Companies in Australia and Canada are exploring germanium-rich mining projects, while Hong Kong Sinomine Rare Metals is pushing to commercialize germanium production at its copper smelting line in Namibia. Belgium’s Umicore, meanwhile, has secured a deal with STL1 in the Democratic Republic of Congo to optimize domestic refining of germanium, further diversifying its global supply.

The rising price of germanium is likely to drive more refining and recycling initiatives, unless alternative materials become more widely adopted in its key applications.
