Introduction
Niobium is a soft, stretchable transition metal whose oxide, niobium pentoxide, behaves like aluminium oxide and zinc oxide to form a protective layer that prevents corrosion.
When added to stainless steel, niobium enhances resistance to fracture at high temperatures, reduces overheating sensitivity and temper brittleness, and improves strength, toughness, and high-temperature creep performance.
Niobium plate has a small thermal neutron absorption cross section, excellent corrosion resistance, and high strength at elevated temperatures, making it ideal for nuclear reactor structural materials, nuclear fuel cladding, and nuclear fuel additives.
Additionally, niobium exhibits a high superconducting transition temperature, and its compounds and alloys are key materials in the superconducting industry.
