Germanium Dioxide PropertiesGermanium dioxide comes as a white powder, or a colorless crystal. There are two types of germanium dioxide: a slightly-soluble hexagonal crystalline system (stable under low temperatures) and an unsoluble tetragonal crystalline system. Its transformation temperatures is 1033degC.
Germanium oxide is insoluble with water and hydrochloric, but it can be converted to germanate by lye. Germanium dioxide with hexagonal structure has more of a rutile like structure and is more soluble in the water. It can also produce germanic acid by interacting with water. When germanium oxide and germanium powder is heated together at 1,000degC, it can produce germanium monoxide.
Germanium Dioxide Applications1. Germanium dioxide, which is also used for electronic industry purposes, can be made from germanium.
2. Germanium oxide is used in semiconductors. The germanium dioxide is created 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, a catalyst when preparing polyethylene terephthalate, and a semiconductor.
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 metals such as germanium and germanium compounds.
