Germanium dioxide
This inorganic compound has the molecular formula of GeO2, and its electronic formula is the carbon dioxide formula. Germanium oxide is used primarily to make metal-germanium. It can also be used for spectroscopy or as a semiconductor.
Germanium Dioxide Properties
Germanium dioxide comes as a white powder, or a colorless crystal. There are two types of germanium dioxide: a hexagonal crystal system which is slightly soluble (stable at lower temperatures) and insoluble tetragonal. Its transformation temperatures is 1033degC.
Germanium oxide is not soluble in water or hydrochloric, but it can be made soluble by lye. Germanium dioxide rutile-like is more soluble in lye than hexagonal germanium and can generate germanic acid upon interaction with water. When germanium oxide and germanium powder is heated together at 1,000degC, it can produce germanium monoxide.
Germanium Dioxide Applications
1. Germanium dioxide, which is used for the production of germanium as well as in the electronics industry, can also be found.
2. Germanium oxide is used in semiconductors. It is made either by heating and oxidizing germanium (or hydrolyzing germanium chloride).
3. Germanium oxide is used for a variety of purposes, including as a raw materials to produce metallic germanium or other germanium-based compounds, as catalysts in the production of polyethyleneterephthalate resins, and as semiconductor material and a material of spectroscopic analysis.
4. Germanium oxide can be produced into optical glass-phosphors. These can then be used as catalysts for conversion in petroleum refining and dehydrogenation. They can also be adjusted to adjust gasoline fractions.
5. Germanium oxide is also used as a polymerization catalyst. The germanium dioxide glass has better refractive indexes and dispersion, making it suitable for wide-angle lenses and microscopes.
6. The use of germanium dioxide has increased with the technology. It is now used to produce high purity metal germanium and germanium compounds in pharmaceuticals, chemical catalysts, electronic devices, PET resins, etc.
