Germanium Dioxide (GeO2)
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.

Today’s mailbag asks: “I would like to know more about your indium wire options.” I'm glad you asked becasue we have over 60 alloys that contain indium. Indium wire comes with a wide choice of purity levels, diameters, and custom packaging options.
When you are doing your year-end clean-up, check to see if you have any indium seals or scrap pieces of indium laying around. Send us your scrap indium and we'll pay you for it or you can use it as a credit on your next purchase of indium wire or preforms.
A new paper sparked my interest recently: Experimental Thermal Energy Assessment of a Liquid Metal Eutectic in a Microchannel Heat Exchanger Equipped With a (10Hz/50Hz) Resonator which talks about alternatives to liquid metal for high-temp heat exchange applications. Unfortunately, they left out my favorite alloy - eutectic gallium-indium or EGaInTM.
