Ruthenium Thin Film Disk (Mylar® Backing)

Ruthenium Thin Film Disk offers high catalytic activity, exceptional corrosion resistance, and excellent electrical conductivity in a precisely machined circular format coated with a uniform thin film. This combination supports applications in microelectronics, electrocatalysis, and optical devices. Industries employ these disks in microcircuit fabrication, reference electrodes, and high-durability sensor interfaces. Research applications include thin-layer electrochemical studies, catalytic reaction kinetics, and surface modification experiments. The disk format ensures uniform electrical properties and facilitates reproducible testing or device integration, while the thin film structure maximizes active surface area without compromising structural integrity. Its ability to combine precision geometry with ruthenium’s robust chemical and electrical properties makes it a key enabler in high-performance scientific and industrial systems.
