Composition: Rh Form: Sputtering Target Material: Rhodium CAS Number: 7440-16-6 Commodity: Precious Metals Purity: 99.9% (3N)
Rhodium Sputtering Target combines exceptional corrosion resistance, catalytic activity, and high reflectivity in a dense, uniform form optimized for thin-film deposition. The sputtering target geometry ensures consistent material transfer during coating processes, supporting applications in electronics, optics, and catalysis. Industries use rhodium targets for producing reflective optical layers, wear-resistant electrical contacts, and catalytic coatings for emission control systems. Research applications include the fabrication of rhodium-based thin films for hydrogen evolution electrodes, magneto-optical devices, and advanced microelectromechanical systems (MEMS). The ability to deposit high-purity, uniform coatings with controlled thickness makes rhodium sputtering targets vital in both industrial-scale manufacturing and specialized R&D, enabling precision engineering of functional surfaces.
