Composition: In Form: Pellet/Lump Material: Indium CAS Number: 7440-74-6 Commodity: Metals
Indium Pellets exhibit high malleability, low vapor pressure, and strong wetting ability, making them versatile for alloying, bonding, and surface engineering applications. Their uniform particulate form allows precise dosing in metallurgical processes and experimental setups. Industries such as electronics, nuclear technology, and renewable energy use indium pellets in solder formulations, radiation shielding materials, and photovoltaic absorber layers. Specific technologies include bonding of semiconductor wafers, thin-film solar cell production, and thermal management in advanced electronic modules. Research applications investigate indium’s role in low-melting alloys, novel perovskite solar cells, and nanostructured thermal interface materials. The pellet form ensures accurate handling, consistent distribution, and controlled integration into complex systems. Their adaptability and precision make indium pellets a valuable resource in both large-scale manufacturing and high-precision scientific development.
