| Impurities (Ta, O, Fe, W) | traces |
Indicative values: distinguish between reactor grade, commercial grade, RRR superconducting grade and alloys (Nb-1Zr, C-103); tantalum and oxygen content affects valuation. Quality is certified by analysis for every lot.
Physical and mechanical data
| Density | 8.57 g/cm³ |
|---|---|
| Melting point | ≈ 2477 °C |
| Hardness | ≈ 60 – 110 HV (annealed) |
| Elastic modulus | ≈ 105 GPa |
| Superconductivity | Tc ≈ 9.3 K (highest of all pure elements) |
| Structure | body-centred cubic (BCC) |
Annealed niobium is very ductile and cold-workable; properties depend on the supply condition. When anodised it develops coloured oxides (jewellery).
