Germanium Oxide

Germanium Oxide (GeO2) is a pre-cursor to the metallic form of germanium. As a white powder, it is used directly as a catalyst in the production of polyethylene terephthalate (PET) plastic or converted to germane gas (GeH4) for the semiconductor industry. Germanium oxide is also used in the manufacture of phosphors, glass colorants and other electronic compounds.
Sino Santech is a main supplier of 99.999% min germanium dioxide and can sell material in small quantity. Our material has been used in the production of germane gas (GeH4), in the production of PET plastics, as an input material for zone-refined germanium ingots and as a glass colorant.
