Optical fibers used in telecommunications operate by confining the light signal to their core and acting as a waveguide for the electromagnetic light wave.
In order to transport the optical signal, the refractive index at the center of the fiber needs to be raised, which is most commonly achieved by using germanium as a dopant. Both germanium tetrachloride and germanium oxide therefore play an important part in optical fiber manufacturing. The starting material for making optical fibers are preforms made from fused silica, and the germanium doping occurs at the center of these preforms.
In addition to providing germanium tetrachloride and germanium oxide to optical fiber manufacturers, we also provide reclaim services that use material that are collected after our customers’ manufacturing process and process them to reclaim and recycle the germanium metal.

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.
Dr. Ron received a question asking him to verify a calculation used to determine the karat value of various gold-based alloys. It's not as simple as it appears. Read this post to see how Dr. Ron answers the question.
