Uses & Benefits
- Niobium alloys are used in jet engines and rockets and spacecraft, beams and girders for buildings and oil and gas pipelines.
- It is used superconducting magnets in particles accelerators, NMR and MRI equipment.
- Strontium metal is used to producing ferrite magnets as well as refining zinc.
-
By-product of nuclear reactors called Strontium-90 is a radioactive isotope; it is absorbed by tissues and destroys bone marrow and cancer growth.
