Storare: Storing in sealed, dry and cool condition, not exposing to air for long time, avoiding moisture.
Application:
1. Optical glass, petroleum cracking catalyst, lanthanum metal, electronic ceramic material, ferrite magnetic material, agriculture, textile,
2. Applied in making special optical glasses to improves the alkali resistance of glass, and also in La-Ce-Tb phosphors for fluorescent lamps.
3. Gadolinium absorbs neutrons as a metal or salt and is therefore sometimes used for neutron radiography and shielding in nuclear reactors.
4. Like most rare earths, gadolinium forms trivalent ions with fluorescent properties, and salts of gadolinium (III) are used as phosphors in various applications.
