This is the first in the group of platinum group of elements. Most of it is used in wear resistant electrical contacts as a thin layer. There is lots of interest in potential uses of this in electronics.
Ruthenium usually occurs as a minor component of platinum ores.
Use, natural applications or common combinations:
- Resistant contacts
