Metal terbium has multiple uses, mainly involving high-tech fields and specific industrial applications:
Alloy and fuel cell stabilizer: Terbium metal is used to manufacture alloys, especially as a stabilizer in fuel cells, to improve the performance and stability of the cell.
Optical disk: In optical disk, terbium metal is used together with iron and cobalt alloys for computer recording media. Information is written and read by utilizing the reflected light changes of surface magnetization during laser irradiation.
Medical field: Terbium metal has important applications in the medical field.
Other applications: Terbium compounds can also be used as insecticides and drugs for treating skin diseases.
In addition, terbium metal is also used to manufacture magnetostrictive materials and certain high-performance materials.
