Description

High purity Germanium dioxide (GeO2) is a precursor to germanium metal. As a white powder, it is used directly as a catalyst in the production of polyethylene terephthalate (PET) plastics or converted to germanium gas (GeH4).

Further, CNGE is able to produce germanium oxide with purity of 99.999% min, and we can make various sizes, higher purity according to customer requirements.
