Niobium Sputtering Targets (Nb) Information

Niobium, element symbol: Nh, Atomic Number 41, is a VB group metal. Density of 8.57 g/cm' , a melting point of 2477 ° C and a boiling point of 4744 ° C. Niobium is a silver-gray, soft and ductile rare high-melting-point metal. Does not react with air at room temperature and is not completely oxidized when red-hot in oxygen.

Niobium can be directly combined with sulfur, nitrogen and carbon at high temperature.Does not react with inorganic acids or bases, nor does it fall in aqua regia, but is soluble in hydrofluoric acid. The content of niobium in the crust is 20ppa, and the distribution of niobium resources is relatively concentrated.

1. Semiconductor field

Niobium targets can be used to manufacture semiconductor devices such as transistors, integrated circuits, and flat panel displays. Niobium products have good chemical stability and electrical conductivity, and can play a good mask and conductive role in the semiconductor manufacturing process to ensure the stability and reliability of the device.

2. Coating field

Niobium targets can be used as PVD (physical vapor deposition) coating materials for surface treatment of metals, ceramics and other materials to form a wear-resistant and corrosion-resistant protective layer. Niobium products show good film-forming properties and chemical stability during the coating process, which can improve the hardness, adhesion and corrosion resistance of the coating.

3. Medical field

Niobium targets are used in medical equipment, such as artificial joints, dental materials, etc. Niobium products have good biocompatibility, corrosion resistance and fatigue properties, and can effectively improve the safety and reliability of medical equipment.

4. Aerospace field

Niobium targets are widely used in the aerospace field, such as rocket engine nozzles, high-temperature alloys, etc. Niobium products have good high-temperature strength and corrosion resistance, and show good stability and reliability in extreme environments.

Niobium is widely used in steel Superconductor classification, aerospace and atomic energy because of its good superconductivity, high melting point, corrosion resistance and wear resistance.
