Germanium Dioxide Supplier symbol

Germanium first came to prominence in the late 1930s with the development of the solid state electronics. Today, germanium metal is commercially used to manufacture infrared optics and photovoltaic cells, while germanium dioxide (GeO2) and germanium tetrachloride (GeCl4) are used in the production of fiber-optic coatings, PET plastic, specialty gases and phosphors.

SMI Ltd. has been refining high purity germanium dioxide since 2009. We are a supplier of germanium dioxide as well as germanium ingots. Please contact us for a current germanium price or with your specific requirements.
