Crystals of high purity germanium are used in detectors for gamma spectroscopy and the search for dark matter. [91] Germanium crystals are also used in X-ray spectrometers for the determination of phosphorus, chlorine and sulfur. [92] Germanium is emerging as an important material for spintronics and spin-based quantum computing applications.
Two oxides of germanium are known: germanium dioxide (GeO 2, germania) and germanium monoxide, (GeO). [4] The dioxide, GeO 2 can be obtained by roasting germanium disulfide (GeS 2) or by allowing elemental germanium to slowly oxidze in air, [5] and is a white powder that is only slightly soluble in water but reacts with alkalis to form germanates.

Germane is the chemical compound with the formula Ge H 4, and the germanium analogue of methane. It is the simplest germanium hydride and one of the most useful compounds of germanium. Like the related compounds silane and methane, germane is tetrahedral. It burns in air to produce GeO 2 and water. Germane is a group 14 hydride.
Gallium and germanium are used in semiconductors, while germanium is also used in infrared technology, fibre optic cables and solar cells. Antimony is used in bullets and other weaponry, while ...
Just one month after China announced it would curb exports of germanium and gallium, both essential for making semiconductors, its overseas shipments of the materials fell to zero.
In chemistry, germanate is a compound containing an oxyanion of germanium. In the naming of inorganic compounds it is a suffix that indicates a polyatomic anion with a central germanium atom, [1] for example potassium hexafluorogermanate, K 2 GeF 6. [2]
Germanium comes from the Latin word Germania, the Latin name for Germany, which is the country where germanium was discovered. Stannum comes from the Latin word stannum , meaning "tin", from or related to Celtic staen .
China's export controls on some gallium and germanium products take effect on Tuesday with traders braced for a drop in international supply in August and September while exporters sort out newly ...
