Two semiconductor metals with concentrated Asian supply — germanium for fiber optics and infrared, indium for touchscreen ITO coatings.
Germanium: Germanium is critical for fiber optic communications, military infrared systems, and aerospace solar cells. China's 2023 export controls directly threaten Western defense and telecom supply chains.
Indium: Indium is essential for every touchscreen and flat panel display. The global smartphone and solar industries depend on stable indium supply from a highly concentrated market.
Germanium: Germanium is a semiconductor metalloid used in fiber optics, infrared optics, solar cells, and night-vision technology. China controls over 80% of global germanium production and imposed export controls in 2023. Indium: Indium is a soft, silvery metal used primarily in indium tin oxide (ITO), the transparent conductive coating on touchscreens, flat panel displays, and solar panels.
As tracked by Critical Minerals HQ, Germanium is currently $1,400 USD/kg and Indium is $167 USD/kg. The two minerals are quoted in different units (USD/kg vs USD/kg), so see the live price panels above for the most recent figures.
Neither is "better" in absolute terms — each is engineered for different end-uses. Germanium is primarily used for: Fiber optic cable components, Infrared optics and thermal imaging, Satellite and concentrator solar cells, Night-vision and defense systems. Indium is primarily used for: Indium tin oxide (ITO) for touchscreens and displays, CIGS thin-film solar panels, Low-melting alloys and solders, Semiconductor compounds for LEDs. The right mineral depends on the application.
Germanium and Indium are quoted in different units (USD/kg vs USD/kg), so a direct numeric rarity comparison from spot price alone is indicative only. See the indexed 25-year chart on the live page for relative scarcity behavior.
Specific US import-reliance percentages are not in our on-file reference text for either Germanium or Indium. See the official USGS Mineral Commodity Summaries for the latest figures.
Germanium top producers (USGS): China, Russia, Canada, United States. Indium top producers: China, South Korea, Japan, Canada. The mineral whose first-listed producer accounts for a larger share of global output carries the greater supply-chain concentration risk.
