Indium
Refined for work where a part per billion of anything else would show up in the measurement.
Indium broken down into small granules, the size that makes weighing out an exact dose simple.
Indium rolled flat into a sheet soft enough to fold, seal or mount by hand.

Applications
At 7N5, indium serves the most impurity-sensitive applications: compound semiconductor growth, ultra-pure alloys and solders, and low-temperature research. Indium's softness and low melting point also make it the standard sealing and contact metal in cryogenics.
- III-V semiconductor growth (InP, InAs, InSb source material)
- Cryogenic seals, gaskets and thermal interfaces
- Ultra-pure solders and specialty alloys
Granule is the working form of indium for anything that starts with melting: alloy and solder preparation, evaporation charges, and compound synthesis. The 5N grade keeps trace metals low enough for semiconductor and vacuum work.
- Alloy and low-melting solder preparation
- Evaporation source charges for thin films
- III-V and chalcogenide compound synthesis
Indium foil is the standard soft-metal consumable of surface science and cryogenics: powders are pressed into it for XPS and SEM analysis, it forms compliant thermal interfaces between cryostat stages, and it seals and solders to glass, ceramics and coated substrates.
- Sample mounting for XPS, SEM and surface analysis
- Thermal interface layers and gaskets in cryogenics
- Soldering and sealing to glass and ceramics
