Product Description

Ge content ≥ 99.999%, resistivity ≥ 50Ω • cm (20 ± 0.5 ºC). Silver gray metallic luster, cuboid bar shape, hard and brittle, melting point of 937.4 ºC, boiling point of 2800 ºC, density of 5.325g/cm3. Germanium is mainly used as a semiconductor material for transistors. The first generation of semiconductors were based solely on germanium. However, most of today's semiconductor production is based on silicon and germanium use in electronics are in fibre-optic systems, infrared optics and in solar cell applications.
