Product Code : RE-Tm2O3-5N-PO
Thulium Oxide, also called Thulia, is the important dopant for silica-based fibre amplifiers, and also have 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 air or in water. This makes Thulium lasers attractive for laser-based surgery.

Product Information
Thulium Oxide, also called Thulia, is the important dopant for silica-based fibre amplifiers, and also have 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 air or in water. This makes Thulium lasers attractive for laser-based surgery. It can also be used in portable X-ray devices that has been bombarded in a nuclear reactor as a radiation source. Thulium oxide (Tm2O3) is a pale green compound. Thulium oxide can be produced by burning thulium metal in air, or by decomposition of their oxoacid salts such as thulium nitrate. It is hygroscopic and absorbs water and carbon dioxide from the atmosphere. Due to the nature of Oxide compounds, Thulium oxide is not conductive to electricity. However, Thulium oxide has several applications in fuel cells and oxygen generation systems. Thulium, atomic no. 69, symbol Tm, weight at 168.94, An important application of the thulium in the Medicine area, and relatively independent of its high cost, is the production of portable X-ray sources. These sources are available for about one year, as tools in medical and dental diagnosis, as well as to detect defects in mechanical and electronic inaccessible components. This type of sources does not need excessive protection. Usually a small cap of lead is enough. Thulium can also be used in magnetic and ceramic materials (ferrite), similar to the yttrium-iron alloys, nowadays used in the microwave technologies.
