Commodity
Germanium
Germanium is a by-product metal with no market of its own. It is recovered mainly from zinc processing residues and some coal fly ash, so its availability depends on decisions taken for other reasons.
Price
No published price
Germanium is assessed by specialist trade services behind subscriptions. There is no free, legal and reliable feed, so we publish no figure rather than one we cannot stand behind.
What it is used for
- Infrared optics, including thermal imaging
- Fibre-optic cable
- Satellite solar cells
- Polymerisation catalysts
Supply
There is no exchange price and assessments are published by specialist trade services. Export controls have made supply a strategic question rather than purely a commercial one.
