Germanium Dioxide Characteristic
1. Germanium dioxide, also called germanium oxide and germania, is the inorganic compound with the
chemical formula GeO2.
2. It is the main commercial source of germanium. Heating germanium dioxide with powdered germanium
at 1000 °C forms germanium monoxide (GeO).
3. The refractive index (1.7) of germanium dioxide and optical dispersion properties makes it useful as an
optical material for wide-angle lenses and in optical microscope objective lenses.
