made with Nb-Zr wire, which retains its superconductivity in strong magnetic fields. This type
of application offers hope of direct large-scale generation of electric power.
Isotopes
Eighteen isotopes of niobium are known. The metal can be isolated from tantalum, and prepared
in several ways.
Cost
Niobium metal (99.5% pure) is priced at about $75/lb.
