Zirconium Thin Film Disk (Mylar® Backing)

Zirconium Thin Film Disk is a precision-machined form of zirconium designed for thin film deposition processes, combining excellent corrosion resistance, biocompatibility, and thermal stability. In disk form, it ensures uniform deposition and is widely employed in electronics, optics, and energy applications. Industries such as microelectronics, biomedical engineering, and aerospace utilize zirconium thin film disks for functional coatings, diffusion barriers, and biocompatible layers. Specific applications include thin film substrates for capacitors, biomedical coatings for implantable devices, and corrosion-resistant layers in aggressive chemical environments. In research, zirconium thin film disks are studied for dielectric properties, oxidation resistance, and microstructural effects in thin film growth. Their combination of stability, precision, and adaptability ensures they remain essential to innovations in electronics, biomedical coatings, and protective thin film technologies.
