    Main application: High purity germanium dioxide is used in Germanium compounds,chemical catalyst and medical industries.

     

    PackagingThe product is packaged in a PVC container, the net weight of every container is about 1 kg, and the PVC is packed in a cardboard segregated box. Every box contains a net weight of about 20kg.

     

    Physical and chemical properties: Germanium dioxide is a white powdery substance, it has three forms it can have four edges, hexagonal or a polygon. Its melting point is 1115℃, at 1250℃ the germanium dioxide is volatile and is easily dissolved with hydrochloric acid.

     

    Transportation and storage: High purity germanium dioxide should be transported and stored in a dry and non-corrosive environment.
