Germanium oxide (GeO₂) is an inorganic compound that appears as a white powder or colorless crystalline solid. It is also known by several names, including germanium dioxide, germanium(IV) oxide, germanic acid, germania, and dioxogermane.
GeO₂ is an important material in the germanium chemical industry.It is widely used as a feedstock for producing phosphors and semiconductor materials, and it serves as a catalyst in the manufacture of polyethylene terephthalate (PET) resin. Germanium oxide is also a key precursor for synthesizing various other germanium compounds.
