Infobox references. Germanium dioxide, also called germanium (IV) oxide, germania, and salt of germanium, [1] is an inorganic compound with the chemical formula Ge O 2. It is the main commercial source of germanium. It also forms as a passivation layer on pure germanium in contact with atmospheric oxygen.
Germanium tetrachloride is an intermediate for the purification of germanium metal or its oxide, GeO 2. [5] Germanium tetrachloride can be generated directly from GeO 2 (germanium dioxide) by dissolution of the oxide in concentrated hydrochloric acid. The resulting mixture is fractionally distilled to purify and separate the germanium ...
Germanium compounds are chemical compounds formed by the element germanium (Ge). Germanium is insoluble in dilute acids and alkalis but dissolves slowly in hot concentrated sulfuric and nitric acids and reacts violently with molten alkalis to produce germanates ([GeO. 3]2−. ). Germanium occurs mostly in the oxidation state +4 although many +2 ...
Infobox references. Germanium monoxide (chemical formula GeO) is a chemical compound of germanium and oxygen. It can be prepared as a yellow sublimate at 1000 °C by reacting GeO 2 with Ge metal. The yellow sublimate turns brown on heating at 650 °C. [1] GeO is not well characterised. [1]
Germanium is a chemical element; it has symbol Ge and atomic number 32. It is lustrous, hard-brittle, grayish-white and similar in appearance to silicon. It is a metalloid (more rarely considered a metal) in the carbon group that is chemically similar to its group neighbors silicon and tin. Like silicon, germanium naturally reacts and forms ...
Germanium oxide. Germanium oxide may refer to: Germanium dioxide, GeO 2, the best known and most commonly encountered oxide of germanium containing germanium (IV) Germanium monoxide, GeO, a stable but not well characterised compound containing germanium (II) Category: Set index articles on chemistry.
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.
Bismuth germanium oxide or bismuth germanate is an inorganic chemical compound of bismuth, germanium and oxygen. Most commonly the term refers to the compound with chemical formula Bi 4 Ge 3 O 12 (BGO), with the cubic evlitine crystal structure, used as a scintillator. (The term may also refer to a different compound with formula Bi 12 GeO 20 ...
