Product Name:Germanium oxide CAS:1310-53-8 MF:GeO2 MW:104.64 Chemical Properties :White powder, hexagonal, tetragonal, and amorphous. Melting point:>400 �°C(lit.) Density :6.239 g/mL at 25 �°C Efractive index:1.99 Storage temperature: no restrictions. Solubility :ethylene glycol: soluble Specific Gravity:6.239 Water Solubility :0.4 g/100 mL Uses:Germanium oxide has high refractive index and infrared transmission, for which it is used in industrial glasses. It also is used in preparation of high purity grade germanium. Description: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.
