Where does your Germanium Ge come from?
Ge, Si, ZnS, ZnSe, Chalcogenide glass are grown and produced by our side.
There are many factories that produce Germanium, why choose yours?
- We use the raw material that is only collected from germanium-containing coal ash (there is only one raw material), and the zone melting process is stable and less impurities. Other factories recycle germanium-containing waste and then purify it, which the quality varies greatly.
- We can ship Germanium materials with original export licence, original name and value in a short time.
What is the Capacity?
Germanium Ingot, 25 tons per year; Germanium Dioxide, 15 tons per year; Germanium Wafer, 380mm in maximum diameter; Silicon, 400-600 mm in dia; Normal diameter is 100mm for ZnS, ZnSe, CaF2 and MgF2.
