Germanium Crystal (Ge)
Germanium Crystal
As a rare metal, germanium has many remarkable properties. For example, good chemical stability, strong corrosion-resistance, easy processing, high and uniform transmittance, high radiation resistance, high frequency, and good photoelectric performance. The germanium crystal can be used to manufacture semiconductor devices, infrared optics, and solar cell substrates.
