- Description
- Rare and costly, dense, silvery-white metal.
- Uses
- Mixed with tungsten or platinum to make filaments for mass spectrographs. Its main value is as a trace alloying agent for hardening metal components that are subjected to continuous frictional forces.
- Sources
- Found in small amounts in gadolinite and molybdenite. Has a very high melting point.
- Pronounciation (English)
- REE-ni-em
