Boils at 4927 .C, melts at 2468 .C

Notes:
Niobium is soft and ductile when in pure form. It's used alloys, tools, dyes,
and superconductive magnets. It's quite corrosion resistant but needs
protection from oxidation ot temperature in excess of 400 .C. It is useful
in the manufacture of cryogenic electronic devices that draw low power.
