Properties common to all products in this list

Composition: Rh Form: Thin Film Material: Rhodium CAS Number: 7440-16-6 Commodity: Precious Metals Support: Permanent Mylar® 3.5µm
Rhodium Thin Film Disk provides excellent surface reflectivity, chemical inertness, and wear resistance in a precisely machined, thin circular form. Its format is ideal for optical coating substrates, reference electrodes, and catalytic layers. Industries such as optics, electronics, and environmental technology utilize rhodium thin film disks for mirrors in high-intensity light systems, durable reference electrodes in electrochemistry, and catalytic surfaces for emission control. Specific uses include precision reflectors in spectroscopic equipment, substrates for thin-film deposition, and active components in advanced catalytic converters. In research, these disks are critical in surface science, optical metrology, and thin-film growth studies. Their combination of geometry, durability, and material purity ensures relevance in cutting-edge applications.
