Product Description

Ge Germanium Powder 6N (99.9999%) CAS 7440-56-4
Germanium powder is a high-purity form of the element germanium, typically available as a fine, gray powder. Germanium is a metalloid
with valuable semiconductor properties and is widely used in electronics, optics, and metallurgy. Its high refractive index, ability to transmit
infrared light, and compatibility with silicon make it highly desirable in various technological applications.

Features
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.

Product Application

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

Metal pellets are small, spherical or cylindrical pieces of metal that are typically produced through various processes like extrusion,
atomization, or pelletizing. These pellets can be made from a variety of metals including iron, aluminum, copper, nickel,and more.
Their size can vary, but most metal pellets fall within a range of 1 to 10 millimeters in diameter. The production of metal pellets is
highly controlled to ensure uniform size, purity, and properties. This precision makes them ideal for applications where consistency
and performance are critical.
