The niobium target is made from high-purity niobium metal (purity > 99.95%). Niobium is a silver-gray, rare, soft, and ductile transition metal with a high melting point (2468°C), excellent corrosion resistance (resistance to strong acid/alkali corrosion at room temperature < 0.01 mm/year), and good conductivity.

The niobium targets achieve a purity level exceeding 99.95%, characterized by a refined grain size and a fully recrystallized microstructure. The material exhibits excellent triaxial consistency, which, as a cathode sputtering target, facilitates the formation of a highly uniform oxide film. This inert protective layer remains non-reactive with atmospheric elements, ensuring long-term surface stability.

Excellent Properties of Niobium Target

l High density, low resistance, fine grain size

 l High hole mobility in films, high optical transmittance, excellent interface matching

 l Low non-metallic impurities (C, N, O)

 Wide Applications of Niobium Target

l Semiconductor Manufacturing

Niobium target plays a key role in chip manufacturing—through magnetron sputtering, it can deposit a niobium thin film as thin as 200 nm on a silicon wafer. This ultra-thin coating effectively enhances the conductivity and corrosion resistance of integrated circuits, making it one of the core materials for 5G chips and memory devices.

l Optical Device Manufacturing

When niobium target meets optical coating technology, it creates remarkable chemical reactions:

Camera lens coatings: increase light transmittance to 99.7%;

AR glasses coatings: enable selective light transmission;

Laser mirrors: withstand high temperatures up to 1800°C.

These properties make niobium target indispensable in applications ranging from smartphone cameras to telescopes.

l Decorative Coatings

Niobium target is highly favored in decorative coatings due to its unique color adjustability and excellent performance. Through anodizing or magnetron sputtering, niobium coatings can display a range of colors, including blue, purple, and gold, while offering corrosion resistance, high hardness, and biocompatibility. It is widely used in the decorative coatings of high-end watches, jewelry, electronic products, and medical beauty devices.
