A lustrous, brittle, grey metal which is chemically similar to silicon and tin. First discovered in 1886.
Germanium is mainly formed during the production of zinc but also recovered commercially from silver, lead and copper ores.
It is one of the few substances that expands as it solidifies from the molten state. It has the same cubic crystal structure as diamond.
Germanium is a semiconductor and is one of the purest metals on Earth.
