Germanium Statistics and Information - USGS

Germanium is mainly a byproduct of zinc ore processing. It is a hard, grayish-white element; it has a metallic luster and the same crystal structure as diamond; and it is brittle, like glass. In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator. The development of the germanium

Who Discovered Germanium - wanttoknowit.com

 · It is a relatively rare element and is found in only a few minerals on Earth. Even in these minerals the concentration of germanium is quite low. It is for this reason that it was discovered relatively late compared with other similar elements. Let’s find out who discovered this rare element. Who discovered germanium?

Germanium | Ge (Element) - PubChem

The element is a gray-white metalloid. In pure state, the element is crystalline and brittle, retaining its luster in air at room temperature. It is a very important semiconductor. Zone-refining techniques have led to production of crystalline germanium for semiconductor use with an impurity of only one part in 1010.

Germanium – Properties and Applications

In 1886AD, Germanium was discovered by German chemist, Clemens Alexander Winkler. In 1885, a new ore was found in a mine near Freiberg, Germany. The ore contained silver and sulfur. Winkler isolated a new element from the ore and named it as germanium. The name germanium is derived from Germany, which is the native country of Winkler.

Germanium - Uses of Germanium & Properties of Germanium

Germanium, a chemical element places between silicon and tin in Group 14 of the periodic table. A hard, grey-white, lustrous and brittle metalloid acts in properties between metals and nonmetals. The element is mostly distributed in nature, but it’s too reactive to occur free.

Germanium - Uses, Pictures, Characteristics, Properties

Characteristics: Germanium is a lustrous, hard, gray-white semi-metallic element with a crystalline and brittle structure. Germanium also has the unusual property that (like water) it expands as it freezes. Four other elements expand when they freeze; silicon, bismuth, antimony and gallium. It is a semiconductor.

Germanium - Chemistry LibreTexts

Like silicon, germanium naturally reacts and forms complexes with oxygen in nature. Unlike silicon, it is too reactive to be found naturally on Earth in the free (elemental) state. Because it seldom appears in high concentration, germanium was discovered comparatively late in the history of chemistry.
