Niobium is a metal with a grey colour. When it remains in air at room temperature for 30 days, its surface forms an oxide layer that produces a slight blue tint. Quantitative tests show that Niobium retains 96% of its initial mass after 12 hours of chemical exposure; Tantalum retains 95% under the same conditions.
Symbol: Nb Atomic number: 41 Atomic mass: 92.90637 Melting point: 2468℃ Element category: Transition Metal
Niobium, formerly known as Columbium, is a grey metal that may acquire a slight blue tint when exposed to air at room temperature over extended periods. It shows a comparable performance to Tantalum and resists a range of chemical agents. Niobium retains high ductility under standard conditions.
