Germanium Powder Description
Germanium powder is a high-purity, finely ground form of germanium, a lustrous, greyish‐white metalloid of the Carbon Group with physical properties comparable to tin and silicon. Naturally, germanium reacts readily with oxygen to form complexes and is too reactive to exist in its natural state on Earth. Ultra‐high‐purity germanium powder is typically obtained by processes such as zone melting. With validated semiconductor and infrared transmission properties, it is used in electronics, fibre optics, infrared optics and as a catalyst in chemical and polymer manufacture.

Germanium Powder Applications
Semiconductor Industry: Germanium powder is employed as a raw material for the production of germanium wafers and substrates. These wafers serve as critical components in the manufacture of high‐frequency transistors, diodes and other semiconductor devices. Germanium was one of the first materials used in transistor development.
Infrared Optics: Germanium is transparent to infrared radiation. Consequently, germanium lenses and windows are used in thermal imaging cameras, night vision devices and spectrometers operating in the IR range.
Solar Cell Technology: Germanium is utilised in multi‐junction solar cells that convert sunlight to electricity efficiently, particularly in concentrated solar power systems and space‐based solar arrays.
Fibre Optics: Given germanium’s high refractive index, it is incorporated in optical fibres and waveguides to enable efficient transmission of light signals in telecommunications and data transfer systems.
Medical Imaging: Germanium‐based detectors are used in positron emission tomography (PET) scanners for medical imaging. These scanners detect gamma radiation emitted by positron‐emitting isotopes in diagnostic imaging.
Infrared Spectroscopy: Germanium crystals serve as ATR prisms or as analysing crystals in infrared spectroscopy for the examination of a sample’s chemical composition.
Geothermal Sensors: Germanium thermistors are utilised as temperature sensors in geothermal exploration and monitoring systems due to their high sensitivity and stability.
Atomic Physics Research: Owing to its electronic properties, germanium is employed in experiments in atomic physics, quantum information and precision measurements.
Gamma-Ray Detection: Germanium‐based detectors, known as high‐purity germanium (HPGe) detectors, are used for gamma spectrometry in nuclear physics, nuclear medicine and environmental monitoring.
Infrared Cameras: Germanium is used in the manufacture of thermal imaging cameras for applications in surveillance, industrial inspections and military operations.
High‐Performance Electronics: Germanium transistors continue to be employed in specialised applications such as cryogenic electronics and radiation‐hardened electronics for space research.
Materials Research: Germanium powder is used in materials research and development to synthesise new materials and analyse their properties.
