Planetarisches Bohrsches Atommodell von Rhenium (Re)
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
