Overview Get Price; Germanium Chemical Elementreaction water uses . Germanium in zinc ores is heated in the presence of chlorine gas. Germanium chloride (GeCl 4 ) is formed Pure germanium metal is then produced by passing an electric current through molten (melted) germanium chloride This method produces very pure germanium. It is possible to buy germanium that is percent .

 · Germanium is mainly a byproduct of zinc ore processing. It is a hard, grayishwhite 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.

 · Germanium has been known to occur as an impurity in sphalerite for over a century (Urbain 1909), and techniques for its extraction from zinc smelting residues were developed early on, long before it had found any technological appliions (Buchanan 1916, 1917; Dennis and Papish 1921).From the 1930s onwards, due to the advent of new and very sensitive spectrographic analytical methods .

Germanium. Pure germanium is a hard, lustrous, graywhite, brittle metalloid. It has a diamondlike crystalline structure and it is similar in chemical and physical properties to is stable in air and water, and is unaffected by alkalis and acids, except nitric acid.

 · Maximum collector current : to (more than other small case transistors). Gain : 80 to 250 (rarely more than 150). Maximum frequency : to MHz (never higher). Any germanium transistor inside these characteristics, and presenting a leakage current Iceo lower than 500μA should work well in a Fuzz. If well biased, the sound would ...

Germanium is stable in air and water and is unaffected by alkalis and acids, with the exception of nitric acid. It is a poor conductor of electricity but has exceptional properties as a semiconductor material and it is in this area where germanium is primarily used.

The chief ore of germanium is germanite, which contains copper, sulfur, about 7% germanium, and 20 other elements. Germanium is produced as a byproduct of the refining of other metals; there is considerable recovery from flue dusts and from ashes of certain coals with high germanium content.

Germanium is a chemical element. People sometimes use it as medicine. Despite serious safety concerns, germanium is used for cancer, heart disease, hepatitis, glaucoma, and other ...

· The germanium element lump is silvery and looks like a metal, so it is customarily called "metalicl germanium". Actually, it is called "polycrystalline germanium", which is gathered crystals during the process of refining germanium from extracted ore minerals, and it is hard as ceramics, but is brittle.
