Germanium dioxide This inorganic compound has the molecular formula of GeO2, and its electronic formula is carbon dioxide. Germanium oxide is mainly used in the production of metal germanium. However, it can also be used as a semiconductor and spectroscopy material.

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 that is slightly soluble (and stable at low temperatures), and a tetragonal crystalline system that is insoluble. Its transformation temperatures is 1033degC.
Germanium oxide is not soluble in water or hydrochloric, but it can be made soluble by lye. Germanium dioxide with hexagonal structure has more soluble in water. It can also produce germanic acid by interacting with water. Germanium monoxide may be produced by heating germanium powder and germanium oxide together at 1000degC.

Germanium Dioxide Applications

1. Germanium dioxide, which is also used for electronic industry purposes, can be made from germanium.

2. Germanium oxide is used in semiconductors. It is produced by heating and oxidizing germanium, or by hydrolyzing germanium.

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 spectroscopic material.

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. Glass that contains germanium dioxide is more refractory and has better dispersion. It can be used to make wide-angle lenses and cameras.

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 resin etc.
