More info

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

Germanium, in terms of its electrical conductivity, is superior to general nonmetals and inferior to general metals, which is physically called a "semiconductor" and has an important role in the development of solid physics and solid electronics. Germanium has good semiconductor properties such as electron mobility, hole mobility, etc. The development of germanium still has great potential.

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. HM manufactures evaporation grade germanium metal granules, the size of 1mm to 10 mm pieces are in excess of 99.999% pure and can easily be used in vacuum chamber crucibles.

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.

Application:

Germanium has various special properties, which have wide and important applications in the fields of semiconductor, aerospace measurement and control, nuclear physics detection, optical fiber communication, infrared optics, solar cell, chemical catalyst, biomedicine, and so on, which is an important strategic resource. In the electronics industry, alloy pretreatment is also served as a catalyst in the optical industry.

Advantage

  • 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, Hg less than 1 ppm.
  • High purity ingots of 99.999% or higher are analyzed for each batch.
  • ISO9001 and ISO14001 certificated manufacturer.
  • Great technical capability to be a valued and long-term supplier.

Packing:

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.
