Pure germanium powder is a hard, lustrous, gray-white and brittle metalloid. It has a diamond-like crystalline structure. It exhibits similar chemical and physical properties to silicon. Germanium is stable in air and water. It is unaffected by alkalis and acids, except nitric acid. Germanium is an indispensable semiconductor, mainly utilized in transistors and integrated circuits.
Germanium powder: Semiconductors are often made from germanium to which small amounts of arsenic, gallium or other metals. Germanium forms many compounds and its oxides are added to glass to increment the index of refraction for instance glass is utilized in wide-angle lenses and in infrared devices. Through germanium, distinct alloys have been prepared. Semiconductor germanium single crystal detectors can precisely identify radiation sources for instance for airport security.
Germanium powder is utilized as a component of alloys. Moreover, it is also used in phosphors for fluorescent lamps. It is employed in equipment used for detecting and measuring such radiation, such as windows and lenses because germanium is transparent to infrared radiation. The high index of refraction of germanium dioxide renders it valuable as a component of glasses applied in optical devices, for instance, wide-angle lenses for cameras and microscope objectives.
Germania powder (GeO2) exhibits notable properties such as the high index of refraction and low optical dispersion. Because of this, it becomes especially useful for wide-angle camera lenses, microscopy and the core part of optical fibers. This semiconductor element can be replaced titania as the dopant for silica fiber, eliminating the subsequent heat treatment that created the fibers brittle.
Germanium powder is useful for monochromators for beamlines. It is utilized in single crystal neutron scattering and synchrotron X-ray diffraction. The reflectivity has benefits over silicon in neutron and high energy X-ray applications. Crystals of high purity germanium are employed in detectors for gamma spectroscopy and the search for dark matter. Germanium crystals are also applied in X-ray spectrometers for the determination of phosphorus, chlorine, and sulfur.
