Germanium dioxide, also called germanium oxide, germania, and salt of germanium, is an inorganic compound with the chemical formula GeO2. It is the main commercial source of germanium. It also forms as a passivation layer on pure germanium in contact with atmospheric oxygen.
Application :
1. The refractive index and optical dispersion properties of germanium dioxide makes it useful as an optical material for wide-angle lenses, in optical microscope objective lenses, and for the core of fiber-optic lines.
2. A mixture of silicon dioxide and germanium dioxide is used as an optical material for optical fibers and optical waveguides.
3. Germanium dioxide is used as a feedstock for production of some phosphors and semiconductor materials.
4. Germanium dioxide is used in algaculture as an inhibitor of unwanted diatom growth in algal cultures.
