Formula: In
Form: Foil/Film/Sheet
Material: Indium
CAS Number: 7440-74-6
Commodity: Metals
Goodfellow's indium foil is offered with a maximum purity of 99.999% (5N), providing unique properties including low melting point, high ductility, and excellent wetting characteristics. These properties make it invaluable in the production of low-temperature solders, liquid crystal displays (LCDs), and touch screens. In the semiconductor industry, indium foil is a key component in the manufacture of compound semiconductors like indium gallium arsenide, used in high-speed electronics and photonics. Its use in transparent conductive coatings for solar cells and smart windows highlights its role in energy-efficient technologies. For research purposes, high-purity indium foil is crucial for developing new alloys, studying superconductivity, and advancing thin-film deposition techniques.
