Key Properties of Pure Niobium
Key Properties:
- Light gray refractory metal with a high melting point (2477°C).
- Low density (8.57 g/cm³), similar to nickel and copper; the lightest refractory metal.
- Highly ductile at room temperature and protected by Nb₂O₅ pentoxide layer.
Applications:
- Key for nickel-based superalloys in aerospace due to strength and heat resistance.
- Used in superconducting magnets for medical and research due to superconductivity.
