Germanium

Name Origin
Latin: Germania (Germany).
"Germanium" in different languages.

Sources
Obtained from refining copper, zinc and lead. It can be found in argyrodite (Ag8GeS6), coal, germanite (Cu13Fe2Ge2S16), zinc ores as well as other minerals. About 80 tons are produced each year.
Uses
Widely used in semiconductors, infrared prisms (for night vision goggles), reflectors in projectors, wide angle lenses and dentistry.
Germanium transistors are still used in some effects pedals by musicians who wish to reproduce the distinctive tonal character of the "fuzz"-tone from the early rock and roll era. Vintage effects pedals known to contain germanium transistors have shown marked increases in collector value for this reason alone.
