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.
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. [4] The monoxide, germanous oxide, can be obtained by the high temperature reaction of GeO 2 with Ge ...
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 ]
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 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 ...

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 ...
