Vanadium Thin Film Disk

Vanadium Thin Film Disk is a precisely machined form of vanadium foil or sheet shaped into disk geometry, optimized for thin film studies, catalysis, and optical testing. Its high purity and controlled dimensions make it ideal for surface science, spectroscopic experiments, and thin film deposition substrates. Industries such as electronics, catalysis, and materials research employ vanadium thin film disks for electrochemical tests, catalytic support structures, and thin film growth experiments. Specific applications include use as electrode substrates in electrochemical cells, sample disks for X-ray photoelectron spectroscopy, and carriers for sputtered or evaporated thin films. In research, vanadium thin film disks are investigated for catalytic activity, oxidation kinetics, and hydrogen storage interactions. Their versatility and surface-specific behavior ensure ongoing value in catalysis, surface science, and thin film technology development.
