Description and Uses
Germanium oxide also called Germanium dioxide is the oxide of germanium, an inorganic compound, featuring the chemical formula GeO2. It is formed as a passivation layer on pure germanium after exposure to oxygen. Germanium dioxide generally has a low toxicity, but shows severe nephrotoxicity at higher doses. Germanium dioxide is still offered on the market in some questionable miracle therapies. Exposure to high doses of germanium dioxide can lead to germanium poisoning.
Germanium oxide can be used in Phosphors, transistors and diodes, infraredtransmitting glass.
