| (u) In X-ray screen |
Options:
Answer:
Solution:
Lanthanoid oxides are used in X-ray screens due to their high atomic number and fluorescence properties → (U).
Lanthanoid metals are used in television screens for phosphor materials → (P).
Misch metal (mixture of lanthanoids + iron) is used in steel production iron alloys → (S).
Magnesium-based alloys are used in bullets and lightweight strong materials → (T).
Mixed oxides of lanthanoids are used in petroleum cracking catalysts → (R).
