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.
- It is used to produce indium tin oxide (ITO), it is used in manufacturing touch screens, flat screen TVs and solar panels.
- Its nitride, phosphide and antimonide are used in transistors and microchips.
