3 Uses
3.1 Uses & Benefits
- 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.
- Tungsten and its alloys are used in high-temperature applications like welding electrodes, high-temperature furnace, etc.
- Tungsten carbide is very hard and used in metal working, mining and petroleum industry.
