High-purity germanium is a semiconductor material. It is obtained by reducing from high-purity germanium oxide and then smelting. Germanium single crystal doped with trace specific impurities can be used to make various transistors, rectifiers and other devices. Germanium compounds are used to make fluorescent plates and various high refractive index glasses.
