Germanium metal(Ge) is a grayish-white element, similar to tin or silicon in appearance, chemical function, and other properties. Pure germanium is produced as a by-product of processing certain zinc ore and coal. Over a third of the demand for elemental germanium is met by recycling.


Germanium has a long history of applications thanks to its unique electrical and optical properties.

Semiconductors. Pure germanium is a critical component in many semiconductors. In the earliest days of semiconductor electronics, germanium was indeed the semiconductor material. In modern usage, germanium is about 1/50th as widely used as silicon and silicon compounds. That said, cutting-edge electronics are increasingly looking to germanium compounds as a potential material, with germanium-silicon replacing gallium-arsenide in some roles.

Optics. While germanium is of reduced value in semiconductor applications today, it is increasingly important in optical applications and materials. Germanium and its compounds are used in fibre-optics, solar cells, infrared optics, LEDs, and dozens of other optical and photovoltaic applications. 

Alloys and compounds. Germanium is also frequently used in chemistry and metallurgy to introduce tarnish resistance, fireproofing, and other benefits to the end material.

AHP Materials offers elemental germanium metal at 99.99%, 99.999%, and 99.9999% purity. We may also be able to fill custom orders for unlisted purities or preparations.
