Indium is a soft, silverywhite metal known for its malleability, low melting point, and excellent wetting properties. It is widely used across the semiconductor, automotive, electrical, and aerospace industries.
In semiconductor manufacturing, highpurity indium is essential for growing III–V compound semiconductor single crystals, including:
- Indium Phosphide (InP)
- Indium Gallium Arsenide (InGaAs)
- Indium Antimonide (InSb)
These materials enable the production of highspeed electronics, optoelectronic devices, infrared detectors, and advanced communication components.
Highpurity indium is also used as a source material for molecular beam epitaxy (MBE), where precise control of purity and deposition is critical for both semiconductor research and commercial device fabrication.
