About Gallium

Gallium is a technology metal critical to advanced semiconductor compounds including gallium arsenide and gallium nitride. These compounds are essential for 5G infrastructure, military radar, satellite communications, and high-efficiency solar cells. China produces the vast majority of primary gallium, and its 2023 export restrictions on gallium highlighted severe supply chain vulnerabilities.
