Uses & Benefits
- Iridium has an anti corrosion properties and it is used in special alloy with Osmium metal and that alloy is used in pen tips and compass bearings.
- Ytterbium metal is used in memory devices and tuneable laser.
-
It is also used as industrial catalyst as the other catalysts are too toxic and polluting.
