Aplicaciones

Lanthanum(III) oxide is used as a precursor to LAMOX fast ion conductors and superconductors. It is also used in the manufacture of optical glasses, piezoelectric and thermoelectric material. It is also useful for X-ray imaging intensifying screens, phosphors as well as dielectric and conductive ceramics. In addition, it is used as a catalyst to effect certain organic transformations. It is one of the active ingredients and finds application in thermoelectric and piezoelectric materials.

Notas

Hygroscopic and moisture sensitive. Incompatible with mineral acids and oxidizing agents. It can convert into lanthanum hydroxide by absorbing moisture.
