Siridion® GTC

Germanium tetrachloride (GeCl4) is a colorless liquid. It is used as an intermediate in the production of purified germanium dioxide and germanium metal, but more predominantly used as a reagent in fiber optic production.

Anwendungsbereich

In fiber optics, germanium tetrachloride is converted into germanium dioxide and then deposited, along with silicon dioxide, using vapor deposition techniques. Germanium dioxide provides a higher refractive index fiber core, which prevents signal loss during transmission.
