Description of Niobium Sputtering Target
As a typical representative of high-melting-point refractory metals, niobium has important applications in superconducting devices, aerospace, and medical implants due to its superconducting properties, corrosion resistance, and biocompatibility.
The purity of our niobium targets can reach more than 99.95%, with the advantages of small grain size, good recrystallization structure, and good triaxial consistency. As a cathode sputtering target, the oxide film formed by it has a uniform mass distribution and will not react with other substances in the air, which has a long-lasting protective effect.

Preparation Method of Niobium Sputtering Target
Vacuum electron beam melting: First, the unforged niobium bars are melted into niobium ingots through a vacuum electron beam melting furnace, usually using two melting steps.
Ion beam sputtering: Suitable for the preparation of high-purity and high-uniformity thin films.
Environment and safety
No pollution: The sputtering process is a dry process, without chemical pollution.
Vacuum annealing and recrystallization: During the sputtering process, the surface of the niobium target is continuously bombarded by high-energy ions, which play the role of vacuum annealing and recrystallization.
