Germanium is mined primarily from sphalerite (the primary ore of zinc), though germanium is also recovered commercially from silver, lead, and copper ores. Elemental germanium is used as a …

Dec 9, 2025 · germanium (Ge), a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the …

Germanium is a semiconductor. The pure element was commonly doped with arsenic, gallium or other elements and used as a transistor in thousands of electronic applications. Today, however, other …

Germanium’s graphical representation features an image of a transistor, which indicates the early use of the element [1]. Being a metalloid, germanium has the properties of both nonmetals and metals [6].

What is germanium classified as? Germanium is a metalloid, meaning it has properties of both metals and non-metals—making it ideal for semiconducting applications.

The existence of germanium was predicted by Russian chemist Dmitri Mendeleev (1834-1907), who developed the periodic table. Mendeleev predicted a new element would be found to fill an empty …

Jan 15, 2026 · In its elemental form, germanium is a brittle grayish white semi-metallic element. Germanium is too reactive to be found naturally on Earth in its native state. It is commercially …

With the discovery of germanium with atomic number 32, Winkler confirmed a theoretical assumption of Dmitri Ivanovich Mendeleev, the inventor of the periodic table of the elements.

The element germanium is a lustrous and brittle metalloid in the carbon group. Germanium is used for optics and electronics.

The most common use of germanium is as a semiconductor in electronics. Germanium is used in transistors and in integrated circuits. It is used as an alloying agent and as a catalyst. It is also used …
