Introduction
Lutetium Foil is a high-purity rare-earth metal product valued for its exceptional density, thermal stability, and chemical performance. As the heaviest of the lanthanide series, lutetium (Lu) is widely used in advanced research, electronics, and specialty materials development where precise material properties and consistency are essential.
Detailed Description
Lutetium foil is produced from refined lutetium metal through carefully controlled melting, rolling, and annealing processes. These steps ensure uniform thickness, smooth surface finish, and stable mechanical properties across the entire foil area. High purity is critical, as trace impurities can significantly affect electrical behavior, surface reactivity, and downstream processing results.
Due to lutetium’s high melting point and excellent resistance to oxidation at room temperature, Lu foil is suitable for high-temperature and vacuum environments. The foil form provides a large surface area and precise thickness control, making it ideal for evaporation sources, alloy research, diffusion studies, and fundamental materials science experiments.
Customized thicknesses, widths, and sheet dimensions can be supplied to meet specific experimental or industrial requirements.
Applications
Thin film deposition and evaporation source material
