Lutetium (III) oxide ? Strategic Elements
Lutetium (III) oxide is a chemical compound of the elements lutetium [Lu] and oxygen [O] and belongs to the group of metal oxides. Furthermore to the lanthanoids and thus also to the group of rare earths.

The world production of lutetium in the form of lutetium (III) oxide is about 10 tons per year. Lutetium (III) oxide is a white, fine powder. It is almost insoluble in water, but soluble in acids. It is hygroscopic and it also absorbs carbon dioxide. In connection with acids, the oxide reacts to form cations, which in turn react weakly acidic in water. Like the other trivalent oxides of the heavier lanthanides, it crystallizes in the cubic lanthanide-C structure with a = 1039 pm and Z = 16. It has a high absorption coefficient for X-rays, which makes it interesting as a scintillation material for medical detectors.

Lutetium (III) oxide is used for the production of special glasses and also as a catalyst in cracking, for alkylation, hydrogenation and polymerization. It also serves as a raw material for the production of laser materials. A compound of lutetium (III) oxide and palladium (II) oxide (generated at high pressure and temperature in the presence of potassium chlorate) has properties that are of interest for superconducting materials.
