Thulium Oxide Powder (Th2O3), CAS 12036-44-1
Thulium oxide powder (Tm2O3) is a light pink powder that is commonly used as a raw material for the production of other thulium compounds, such as thulium metal, thulium fluoride, and thulium nitrate.
Thulium oxide is insoluble in water, but soluble in acids. It has a high melting point of 2,308 °C and a high thermal conductivity, making it useful in high-temperature applications. It is also used as a green phosphor in television screens, as a dopant in the production of solid-state lasers, and as a glass colorant.
Thulium oxide powder should be stored in a cool, dry place, away from heat sources and incompatible materials. Proper protective equipment, such as gloves and safety goggles, should be worn when handling this material.

Application
Thulium Oxide, also called Thulia, is the important dopant for silica-based fiber amplifiers, and also has specialized uses in ceramics, glass, phosphors, lasers. Because the wavelength of Thulium-based lasers is very efficient for superficial ablation of tissue, with minimal coagulation depth in the air or in water. This makes Thulium lasers attractive for laser-based surgery. It can also be used in portable X-ray devices that have been bombarded in a nuclear reactor as a radiation source.
