Thulium Oxide

Preparation

Thulium- and ytterbium-rich solutions were prepared from yttrium niobium ore through a series of extraction steps. These solutions were then separated by oxalic acid precipitation, filtered, and calcined to obtain thulium oxide.

Tm2(C2O4)3→Tm2O3+3CO2+3CO

Uses

Thulium oxide is used in the production of laser agents, electronics industry, scientific research, metal alloys, neodymium iron boron permanent magnet materials, chemical additives, etc.; it can also be used to manufacture portable X-ray transmission devices and as a control material for reactors.
