- Germanium Oxide Powder Typical Applications:
a) Used in the manufacture of optical glass and as a drug in the treatment of pernicious anemia. Also limited applications as a replacement for glass in microscope objectives.
b) Germanium dioxide's refractive index (1.7) and optical dispersion properties make it useful as an optical material for wide-angle lenses and in optical microscope objective lenses. It is transparent in infrared.

c) Germanium dioxide is also used as a catalyst in production of polyethylene terephthalate resin, and for production of other germanium compounds. It is used as a feedstock for production of some phosphors and semiconductor materials. In the manufacture of integrated circuits and transistors, germanium dioxide is a rather poor dielectric and is chemically unstable, which is one of the disadvantages of germanium in comparison with silicon.
