Applications for Niobium
Niobium Product Application Technical Attributes/Benefits
HSLA Ferro-niobium (~60%Nb) Niobium additive to ‘high strength low alloy’ steel and stainless steel for oil and gas pipelines, car and truck bodies, architectural requirements, tool steels, ships’ hulls, railroad tracks. Imparts a doubling of strength and toughness due to grain refining. Weight reduction.
Niobium oxide - Manufacture lithium niobate for surface acoustic wave filters.
- Camera lenses.
- Coating on glass for computer screens.
- Ceramic capacitors. - High index of refraction.
- High dielectric constant.
- Increase light transmittance.
Niobium carbide Cutting tool compositions. High temperature deformation, controls grain growth.
Niobium powder Niobium capacitors for electronic circuits. High dielectric constant, stability of oxide dielectric.
Niobium metal plates, sheets, wire, rod, tubing - Sputtering targets.
- Cathode protection systems for large steel structures.
- Chemical processing equipment. Corrosion resistance, formation of oxide and nitride films. Increase in high temperature resistance and corrosion resistance, oxidation resistance, improved creep resistance, reduced erosion at high temperatures.
Niobium-titanium alloy
Niobium-tin alloy Superconducting magnetic coils in magnetic resonance imagery (MRI), magnetoencephalography, magnetic levitation transport systems, particle physics experiments. Electrical resistance of alloy wire drops to virtually zero at or below temperature of liquid helium (-268.8°C).
Niobium-1%zirconium alloy - Sodium vapor lamps
- Chemical processing equipment Corrosion resistance, fixation of oxygen, resistance to embrittlement.
Vacuum-grade ferro-niobium and nickel-niobium Superalloy additions for turbine blade applications in jet engines and land-based turbines. Inconel family of alloys, superalloys. Increase in high temperature resistance and corrosion resistance, oxidation resistance, improved creep resistance, reduced erosion at high temperatures.
