The Periodic Element Guys present 99.9999% Pure Germanium Crystalline. Germanium is an important semiconductor material. It is commonly doped with arsenic or gallium at the level of one part per 1010 for electronics. Germanium is also used as an alloying agent, a catalyst, and as a phosphor for fluorescent lamps. The element and its oxide are used in highly sensitive infrared detectors and other optical devices. The high index of refraction and dispersion of germanium oxide has led to its use in glasses for use in microscope and camera lenses. Organic germanium compounds have relatively low toxicity to mammals, but are lethal to certain bacteria, giving these compounds potential medical importance.
