Come see Indium Corporation's new AuLTRA™ ThInFORMS™ at SPIE West in San Francisco, CA Feb. 4-6, 2020. AuLTRA™ ThInFORMS™ improve thermal transfer and the overall operational efficiency of die-attach applications.
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) 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.
