Buy single - crystal germanium in Astana at the price of the manufacturer LLP "KMI Company"
Germanium metal is a gray - white solid with a metallic luster. Metallic germanium is stable in air at room temperature and quickly oxidizes at temperatures above red heat (600 - 700 ° C) with the formation of dioxide, does not react with nitrogen, hydrogen.
To obtain single - crystal germanium, the starting material (polycrystalline zone - cleaned germanium) is assembled with the addition of a dopant, cleaned of impurities and an oxide film by chemical etching, and loaded into a furnace. Production is regulated in accordance with GOST 16153 - 80.
Germanium is a semiconductor material widely used in electronics and engineering, as well as in the production of microcircuits and transistors. Radar installations use thin films of germanium, which are applied to glass and used as resistance. Alloys with germanium and metals are used in detectors and sensors.
