Description

  • General description: 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.
  • Application: 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.
  • Features and Benefits: High refractive indexLow dispersionColorless in the glass matrix Efficient, inexpensive, and recyclable catalyst
