Material Notes:
Germanium dioxide is a white powder that is manufactured in both crystalline and amorphous forms. Germanium dioxide's refractive index (1.7) and its optical dispersion properties are useful for making wide-angle lenses and optical microscope objective lenses. It is transparent to infrared light.Germanium dioxide is also used as a catalyst in the production of polyethylene terephthalate (PET) resin and in the production of other germanium compounds, as well as some phosphors and semiconductor materials.Characteristics:Synonyms: Germanium (IV) Oxide, GeO2CAS Number: 1310-53-8EC Number: 215-180-8RTECS: LY5240000Purity: 99.999%Appearance/Form: White powderCrystal structure: HexagonalSolubility: Soluble in Alkalis. Slightly Soluble in Acids. Slightly soluble in Water.Information provided by the manufacturer, Indium Corporation of America.
