WebAug 15, 2024 · Germanium. Germanium is a rare element used in the manufacture of semi-conductor devices. The physical and chemical properties of germanium are very similar to those of silicon. The semi-metal is found in coal, ore, and germanite. Germanium is gray-white in color and forms crystal structures.
Germanium is considered a technology-critical element. Germanium is not thought to be an essential element for any living organism. Similar to silicon and aluminium, naturally-occurring germanium compounds tend to be insoluble in water and thus have little oral toxicity.
