Description

General description

Lanthanum (III) oxide is an alkaline earth oxide, and is a diamagnetic, isostructural analog of neodymium oxide. It is also an efficient recyclable catalyst, and can be used in coupling various aryl halides with aromatic/alkyl thiols.

Application

Lanthanum (III) oxide was used as an analytical standard in inductively coupled plasma atomic emission spectrometry (ICP-AES) for chemical characterization of ancient pottery.

Precursor to LAMOX fast ion conductors and superconductors.

Suitable for use as atomic absorption standard.
