An inorganic compound that has the molecular structure GeO2, the oxide of germanium. The electronic formula is similar to carbon dioxide. Germanium dioxide is used primarily to make metal germanium. It is also used for semiconductor spectroscopy.
Germanium Dioxide Properties
Germanium dioxide, a white powder and colorless crystal, is also known as germanium dioxide. You can choose between a slightly-soluble hexagonal crystal (stable at lower temperatures) or an insoluble Tetragonal crystal system. It has a transformation temperature of 1033°C.
Germanium dioxide cannot be dissolved in water or hydrochloric acids, but can be dissolved in lye in order to make germanate. Germanium dioxide having a rutile structure can be more easily dissolved in water than hexagonal germanium dioxide and it can also produce germanic acids when it interacts. At 1000 degrees Celsius, you can make germanium monoxide by heating germanium dioxide with germanium powder.
Germanium Dioxide Applications
1. Germanium dioxide, which is used for the production of germanium, can also be used in electronic manufacturing.
2. Germanium dioxide is used in semiconductors. You can make it by heating, oxidizing and hydrolyzing germanium.
3. Germanium dioxide is used in preparations of metallic germanium or other germanium compounds.
4. Germanium dioxide can also be used in the production of optical glass, phosphors. This can be used as an aid for conversion during petroleum refinement, dehydrogenation or adjustment, and color film, and polyester fiber manufacturing.
5. Germanium dioxide also acts as a catalyst to the polymerization process. The glass containing germanium dioxide is more flexible and has better dispersion and refractive properties. It can also be used to make microscope lenses or wide-angle cameras.
6. The development of technology has allowed germanium dioxide to be widely used in the production of high-purity metal germanium, compounds made from germanium, chemical catalysts, as well as pharmaceutical industry chemicals, PET resin and electronic devices.
