- 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.
