The two semiconductor metals China hit with export controls in 2023 — both critical for 5G, defense electronics, and fiber optics.
Gallium: Gallium is essential for 5G infrastructure, defense radar, and next-generation power electronics. China imposed export controls on gallium in 2023, creating immediate supply disruption.
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.
Gallium: Gallium is a critical technology metal used in gallium arsenide (GaAs) and gallium nitride (GaN) semiconductors. GaN chips are the foundation of 5G wireless networks, radar systems, and next-generation power electronics. 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.
As tracked by Critical Minerals HQ, Gallium is currently $230 USD/kg and Germanium is $1,400 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. Gallium is primarily used for: GaN semiconductors for 5G and power electronics, GaAs chips for solar cells and radar, Blue and violet LEDs and laser diodes, Integrated circuits for defense electronics. Germanium is primarily used for: Fiber optic cable components, Infrared optics and thermal imaging, Satellite and concentrator solar cells, Night-vision and defense systems. The right mineral depends on the application.
Gallium and Germanium 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 Gallium or Germanium. See the official USGS Mineral Commodity Summaries for the latest figures.
Gallium top producers (USGS): China, Russia, South Korea, Japan. Germanium top producers: China, Russia, Canada, United States. The mineral whose first-listed producer accounts for a larger share of global output carries the greater supply-chain concentration risk.
