Product Name:Germanium
English Name:Germanium
CAS No.:7440-56-4
Aliases:Germanium granules
Molecular Formula:Ge
Physical Properties:Bright silver brittle metal with semiconducting properties. Density approx. 5.323 g/cm³, melting point approx. 938.25°C, boiling point approx. 2833°C. Stable in air at room temperature, insoluble in water, soluble in strong oxidizing acids such as aqua regia and concentrated nitric acid.
Uses:High-purity germanium is an important semiconductor material. Germanium single crystals doped with trace specific impurities can be used to manufacture transistors, rectifiers and other electronic devices. Germanium compounds are used in fluorescent plates and high-refractive-index glass, and it is also widely applied in infrared optics, optical fiber communication and solar cells.
