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 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.
