Gallium Compounds

Germanium Compounds

Our germanium compounds include germanium tetrachloride (GeCl4) and germanium oxide (germanium dioxide, GeO2).

Features & Benefits

We supply both materials at high purities. The optical fiber and semiconductor industries are the main users of these compounds.
Germanium Tetrachloride C-m3

Germanium Tetrachloride (GeCl4)

CAS No. 10038-98-9

Germanium tetrachloride (GeCl4) is a colorless liquid. It is used as an intermediate in the production of purified germanium dioxide and germanium metal.

GeCl4 is transparent to infrared light and therefore useful in optical materials. It is also widely used as a semiconductor and as an alloying agent. Silicon-germanium alloys are used for low-cost, high-speed integrated circuits as well as precision optical components, and germanium tetrachloride is an important dopant material in the manufacturing of optical fibers for telecommunications. A further use of germanium dioxide is as a polymerization catalyst, widely used in Japan for the manufacturing of PET bottles for water.

Germanium Oxide SEM

Germanium Dioxide (GeO2)

CAS No. 1310-53-8

Germanium dioxide (GeO2) is a white powder that is manufactured in both crystalline and amorphous forms. Germanium dioxide’s refractive index (1.7) and its optical dispersion properties make it a useful material for wide-angle lenses and optical microscope lenses. GeO2 is transparent to infrared light.

Germanium dioxide is also used as a catalyst in the manufacturing of polyethylene terephthalate (PET) resins, and for the production of other germanium compounds, phosphors, and semiconductor materials.
