Iridium Pellets

Iridium Pellets provide high density, corrosion resistance, and thermal stability in a small, versatile form optimized for controlled dosing in research and production. Their chemical inertness and high melting point make them indispensable in catalysis, electronics, and materials science. Industries employ iridium pellets in catalytic converters, thin-film deposition sources, and doping agents in specialty alloys. Specific technologies benefiting include sputtering targets for thin-film coatings, catalysts for hydrogen evolution reactions, and electrode materials for advanced batteries. Research applications involve pellet-based evaporation studies, nanoparticle synthesis, and alloy microstructure development under extreme conditions. The pellet format ensures accurate handling, reproducibility, and efficient material utilization in both experimental and industrial contexts. By combining form flexibility with iridium’s intrinsic resilience, iridium pellets play a crucial role in advancing catalysis, energy storage, and high-performance electronic applications.
