Indium

Indium is a critical dopant for germanium and a primary component in compound semiconductors such as Indium Phosphide (InP) and Indium Antimonide (InSb) used in high-speed electronics.

Indium is used as a sputtering target material, often alloyed with tin oxide (ITO), to create transparent conductive coatings for touchscreens and flat-panel displays.

High-purity indium pellets and wire are used as evaporation sources in physical vapor deposition (PVD) to form thin films for optical and electronic applications.

Indium is used to create low-melting-point alloys and lead-free solders, improving the thermal fatigue resistance and ductility of the resulting metallic mixtures.

Indium-based compounds are essential for manufacturing laser diodes, LEDs, and photodetectors that operate in the infrared spectrum.
