Niobium Plate/Sheet/Disc Production Process

• Raw Material: Select high-purity niobium powder.
• Powder Metallurgy: Mix with binder and compact into a green billet.
• Sintering: High-temperature sintering to remove the binder and increase density.
• Heat Treatment: Anneal to relieve stress and enhance properties.
• Surface Treatment: Clean and polish the surface.
• Cutting & Customization: Cut or customize according to requirements.

Niobium Plate/Sheet/Disc Surface Finish

Depending on the intended applications, niobium plate, sheet, and disc have three main surface finishes as follows:

• Black: The surface is “as swaged” or “as drawn”, retaining a coating of processing lubricants and oxides.
• Cleaned: The surface is chemically cleaned to remove all lubricants and oxides.

Niobium Plate/Sheet/Disc Applications

• Superconducting Materials: Niobium plates, sheets, and discs are widely used in the field of superconductivity and are commonly employed to produce superconducting cables, superconducting magnets, and other devices, particularly in particle accelerators and nuclear magnetic resonance (NMR) instruments.
• Nuclear Industry: Niobium plates, sheets, and discs are commonly used as structural materials in nuclear reactors and nuclear fuel jacket materials due to their low neutron capture cross-section and high corrosion resistance.
• Aerospace: Due to their excellent high-temperature strength and heat resistance, Niobium plates, sheets, and discs are often used to manufacture high-temperature components, such as engine components for rockets and airplanes.
• Electronic Components: Niobium plates, sheets, and discs are utilized as acid- and liquid-metal-corrosion-resistant materials in the manufacturing of boilers, heaters, and other equipment.
• Chemical Industry: Niobium plates, sheets, and discs are used as acid and liquid-metal-corrosion-resistant materials for boilers, heaters, and other equipment.

Niobium Plate/Sheet/Disc Packaging

The Niobium Plate/Sheet/Disc is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
