Germanium Dioxide:

Germanium dioxide (GeO2) is a pre-cursor to the metallic form of germanium. A white powder, germanium dioxide is used directly as a catalyst in the production of polyethylene terephthalate (PET) plastic or converted to germane gas (GeH4) for the semiconductor industry. While germanium dioxide is itself produced from germanium tetrachloride (GeCl4), optical fibre producers often purchase the the dioxide form for conversion to germanium tetrachloride. GeO2 is also used in the manufacture of phosphors, glass colorants and other electronic compounds.

SMI Ltd. is a low cost producer of 99.999% min. germanium dioxide and can sell material in units from 1kg. 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. We can ship material directly from our Canadian and Chinese offices as required.
