Niobium Metal Plate

Niobium metal plate refers to plates or sheets made of metal niobium (Niobium, chemical symbol Nb). It is an important processed form of niobium metal with a series of excellent properties, which makes it play a key role in many high-tech and industrial fields.

Niobium plate is a refractory metal with high strength and low specific gravity. It has a melting point of 2468 °C and a density of 8.57g/cm3. High-purity niobium metal has high ductility, but it will become harder with the increase of impurity content.

Niobium is very stable in air at room temperature, not easily oxidized, and does not react with most acids and bases, but is soluble in hydrofluoric acid. It can react with oxygen, sulfur, nitrogen, carbon and other elements at high temperatures to form a stable oxide protective layer. Therefore, during use, it must be placed in a protective atmosphere even at moderate temperatures.

Luoyang Rare Metal Research Material Co.,Ltd has rich experience in providing high-quality Niobium Plate and Sheet in different grades and dimensions. There are various forms of the plates, such as the sheet, foils and strips. We can also customize various shapes of niobium products according to your requirements or drawings.

Niobium metal plate has many excellent characteristics:

- Key superconductivity:

Pure niobium has a relatively high superconducting transition temperature (about 9.2K), It is the highest among all elemental superconductors and is the core material for manufacturing low-temperature superconducting devices (especially superconducting radio frequency cavities in particle accelerators).

- Low thermal neutron absorption cross section:

Suitable for use in nuclear reactor environments.

- Excellent low-temperature toughness:

Even at extremely low temperatures close to absolute zero (such as liquid helium temperature), it will not become brittle and still maintain good plasticity.

- Good processing performance:

Compared with other refractory metals such as tungsten and molybdenum, niobium is easier to process by rolling, stamping, forging, etc.

- High melting point:

It is a "refractory metal" and can work at extremely high temperatures.

- Excellent corrosion resistance:

It is especially resistant to hot concentrated acid, molten alkali and liquid metal corrosion, second only to its "brother" metal tantalum. It is very reliable in highly corrosive chemical environments.

- Good biocompatibility:

It is non-toxic and compatible with human tissue and can be used for medical implants.

Niobium metal plate plays a key role in multiple high-tech and industrial fields because of its excellent performance: 

- The "heart" of superconducting technology:

It's the largest and most important application area! Manufacturing superconducting radio frequency acceleration cavities in particle accelerators (such as the Large Hadron Collider LHC). High-purity niobium plates are currently the most mainstream cavity materials.

- "Armor" for chemical corrosion protection:

Manufacturing reactors, heat exchangers, pipes, valves and other equipment or their linings for handling highly corrosive chemicals (especially high-temperature concentrated acids and molten alkalis).

- High-temperature parts for aerospace:

Used in rocket engine nozzles, combustion chamber linings and other parts that need to withstand extreme high temperatures and corrosion.

- "Guardian" of the nuclear industry:

Used as nuclear fuel cladding materials or components in nuclear reactors (because they are corrosion-resistant and do not "eat" too many neutrons).

- High-end electronics industry:

Making sputtering targets for semiconductor coating.

- Biomedical implants:

Manufacturing orthopedic and dental implants (such as bone plates, screws, implants), thanks to their biocompatibility and inertness.

- High-temperature industrial furnace components:

Such as heat shields, boats, heating elements, brackets, etc.

- The niobium plate will be packed in standard export three-ply plywood cases or carton

- Plastic shock absorption foam is tightly filled in the box

- Place desiccant in the box

- Small size will be vacuum-packed
