Ge Germanium Powder 6N (99.9999%) CAS 7440-56-4 CAS NO.7440-56-4

High Refractive Index: Germanium’s high refractive index (around 4.0) makes it ideal for use in infrared optics.

Infrared Transparency: Germanium is transparent to infrared light in wavelengths ranging from 2 µm to 14 µm, making it ideal for thermal imaging and IR optics.

Semiconductor Properties: Germanium has a narrow band gap (0.67 eV) and high electron mobility, making it suitable for high-speed electronic devices and optical communication.

Corrosion Resistance: Germanium is resistant to oxidation and corrosion, which makes it durable in harsh environments.

Application

1. Semiconductors: Germanium powder is primarily used in semiconductor industries for manufacturing transistors, diodes, and other electronic components due to its excellent semiconducting properties.

2. Infrared Optics: Germanium is widely used in infrared optics, particularly for lenses and windows in thermal imaging systems, infrared cameras, and spectrometers. Germanium powder is processed to create components for these applications.

3. Alloys: Germanium is often added to metals to improve their properties. It is used in alloys with silver, aluminum, and other metals to enhance strength and corrosion resistance.

4. Fiber Optics: Germanium dioxide, derived from germanium powder, is used in the production of the core of optical fibers to increase their refractive index and improve light transmission.

5. Solar Cells: Germanium is used as a substrate in high-efficiency solar cells, particularly in space applications where it forms part of multi-junction photovoltaic cells.

6. Catalysts: Germanium powder is used in certain catalysts for polymerization and in the production of polyethylene terephthalate (PET) plastics.

7. Medical Applications: Germanium is researched for potential use in pharmaceuticals and nutritional supplements, although its effectiveness and safety are still under investigation.
