More info

Germanium (Ge), in terms of its electrical conductivity, is superior to general nonmetals and inferior to general metals, It is physically called a "semiconductor" and has an important role in the development of solid physics and solid electronics. It has good semiconductor properties such as electron mobility, hole mobility, etc.

Germanium powder is dark blue, crystalline, and silvery white brittle metal. Compound + 2 and + 4. The first ionization energy 7.899 eV, is a rare metal, an important semiconductor material that is insoluble in water.

Germanium Granule

Germanium Granule is reprocessed by high purity zone refined Germanium ingot in the vacuum and clean workshop. Its purity is 99.999% min with a size range of 1-40 mm.

Germanium Ingot

Zone refining germanium involves passing raw material through a hot zone that creates high-purity molten metal. Impurities collect in the molten material and are pushed back as the germanium metal solidifies as it exits the hot zone.

  • Aerospace measurement and control
  • Nuclear physics detection
  • Optical fiber communication, infrared optics, and solar cells
  • Chemical catalysts
  • Biomedicine


  • Strict raw materials control: raw materials are collected from non-recycled coal ash.
  • Low heavy metal content: the content of Mg, Al, Pb, As, Ni, and Hg less than 1 ppm.
  • High-purity ingots of 99.999% or higher are analyzed for each batch.
  • Great technical capability to be a valued and long-term supplier.


Germanium shall be stored in a cool, ventilated, dry, clean warehouse without a corrosive atmosphere of chemical drugs. Moisture-proof. Do not be stored and mixed with acid and alkali products. Prevent rain and shock prevention during transportation. Carefully during handling and unloading to prevent collision and rolling and prevent mechanical damage.
