Beschreibung

Allgemeine Beschreibung

La₂O₃ is a wide band gap p-type semiconductor with an empty Ln-4f shell and is widely used to prepare optical materials, dielectrics, and conductive ceramics. La₂O₃ can also be used as a catalyst in many organic transformations.

Anwendung

Lanthanum(III) oxide can be used as a dopant to prepare radiation-shielding glasses. For example, it can be added to waste soda-lime glass to improve the linear attenuation coefficient and radiation shielding characteristics of the glass.

It can be used as a recyclable catalytic system for the synthesis of diphenyl sulfides and selenides and for the C-N cross-coupling of aryl halides with heteroaromatic amines.

It can also be used as a promoter or support material for the selective oxidation of methanol over gold catalyst.

Vorläufer für LAMOX-Festelektrolyte und Supraleiter.
