Composition: Re Form: Pellet/Lump Material: Rhenium CAS Number: 7440-15-5 Commodity: Metals Type: Nominally 6mm Thickness x 12mm Diameter Purity: 99.99% Maximum Lump Size: 15mm
Rhenium Pellets offer outstanding high-temperature mechanical strength, chemical inertness, and thermal stability in a compact, easily handled form. The pellet geometry facilitates precise dosing in alloying processes, controlled evaporation in thin-film deposition, and uniform distribution in catalyst beds. Industries use rhenium pellets in superalloy production for turbine blades, in semiconductor coating processes, and in specialized catalysts for petrochemical refining. Research applications include high-temperature materials testing, evaporation source calibration for vacuum deposition, and catalytic performance studies in hydrogenation and reforming reactions. The combination of rhenium’s refractory properties and the pellet’s metered format supports consistent, repeatable use in both industrial-scale manufacturing and laboratory-scale innovation.
