Germanium Oxide GeO2 Powder:
Germanium Dioxide or Germanium Oid has the same electronic structure as carbon dioxide and is an inorganic substance with the molecular form GeO2. It is the Oxides of Germanium. The compound is also called germanium oxide or germanium salt. It is the most important commercial source for germanium. Germanium dioxide exhibits both acidic as well as basic properties. It forms a passivation film when pure germanium in contact with oxygen. There are two types of crystal systems. The transition is at 1033. Metal germanium is the main application, but it’s also used as a semiconductor material and for spectroscopic analysis.
The two main crystallographic forms of GeO2 (a soft mineral) are hexagonal, and tetragonal. The hexagonal GeO2 shares the same structure with b quartz, and the germanium coordinate number is 4. Tetra GeO2 (a softer mineral) has a rutile-like crystal structure found in stibnite. This subject has a coordination number of 6. GeO2 can be amorphous or glassy, similar to silica molten.

Performance and properties of Germanium Oxide GeO2 Powder:

Germanium Oxide, a stable white powder, is most often extracted from sphalerite and fly ash. Germanium concentrates may be treated using a method of chlorine distillation to create germanium Tetrachloride. This form is Germanium Oxide, which has a hexagonal crystalline structure. It dissolves in water at the rate of 4.5g/litre (25degC).

How are Germanium Oxide powder GeO2 manufactured?
Germanium oxide can be produced in both crystalline as well as amorphous shapes. A network of GeO4 is the amorphous form under ambient pressure. The germanium -O bonds distance increases correspondingly when the pressure reaches about 9 GPa. When the pressure reaches around 15 GPa the germanium coordinate number increases to 6. The dense network structure then forms by the GeO6 octahedron. If the pressure is then reduced, the structure reverts back to a tetrahedral configuration. When the pressure is high, the rutile forms are converted into the orthogonal CaCl2 forms.
To hydrolyze the germanium chloride tetrachloride it is necessary to add 6.5x the volume of distilled tetrachloride to distilled water. Stir it and leave it overnight for germanium oxide precipitation. Wash it with cold tetrachloride until the lotion no longer contains Cl. The germanium dioxide product dried at 200.

Germanium dioxide Uses:
Germanium dioxide can be used for a number of different applications.
Germanium dioxide is a material that can be used for optical materials such as wide-angle lenses, microscope objectives and fiber wires.
Germanium and GeO2 glass oxide are both transparent for infrared spectral. The glass can also be used to make infrared lenses and windows for luxury cars, military applications and night vision cameras.
The superior mechanical strength of GeO2 makes it a better choice for rugged military applications.
As optical materials, optical fibers and wavesguides use mixtures of silicon dioxide and Germanium. By controlling the proportions of elements, the refractive indices can be controlled precisely.
Germanium oxide is used in the production process of certain phosphors and semi-conductor materials.
Diatoms can easily absorb GeO2, which results in germanium being replaced by silicon in their internal biochemical process. This causes a significant reduction in diatom growth, or even a complete disappearance. Non-diatoms species are almost unaffected.
Use as a material for semiconductors. Used in electronics to make germanium. It can also be used for the production of germanium and other germanium-based compounds, as well a catalyst to produce polyethyleneterephthalate, and for semiconductor materials. It is a catalyst that can be used for color film, polyester fiber, petroleum refining conversion and dehydrogenation. In addition, the glass containing the germanium dioxide has a high index of refraction and dispersion, making it ideal for wide-angle lenses, microscopes, and cameras. As technology advances, the use of germanium is increasing in many industries, including the pharmaceutical, electronic, and PET resin industries.
