Niobium

• There are a minimum of 32 known radioactive isotopes of niobium. • Heinrich Rose that the tantalum ore included a second element, which he named niobium.• Both names were used until niobium was chosen as the name for this element, in 1949.• Niobium didn't have a commercial use until the 1900s.• Primarily used to mix with other metals.• Niobium mixes produce a special steel for stronger gas pipelines.• Just 0.1%of Niobium improves the structural strength of steel dramatically.

• Reacts with:◦ Fluorine, chlorine, bromine, and iodine• Not toxic• Under most circumstance, niobium is flammable

Standard Phase: Solid Density: 8.57g/cm³ Heat of Fusion: 30kJ/mol Heat of Vaporization: 689.9kJ/mol Specific Heat Capacity: 24.6J/mol·1/K Shiny, white, soft metal

• With iron and other elements in stainless steel mixtures• Used in mixtures with a variety of related metals• Niobium mixtures are strong and are often used in pipeline construction• The metal is used in mixtures for jet engines and heat resistant equipment
