Magnetic Properties
e.g. CrO2, Fe3O4 for recording technology
Optical Properties
Pigments, e.g. TiO2 in paints
Phosphors, e.g. Eu3+ in Y2O3 is red on TV
Lasers, e.g. Cr3+ in Al2O3 is ruby
Frequency-doubling of light, e.g. LiNbO3
Catalysts
Zeolite ZSM-5 (an aluminosilicate)
- Petroleum refining
- methanol octane
Sensors
Oxygen sensor, e.g. ZrO2/CaO solid solution
