Thulium Oxide Tm2O3

Product Detail

Brief information Product: Thulium Oxide Formula: Tm2O3 Purity:99.999%(5N), 99.99%(4N),99.9%(3N) (Tm2O3/REO) CAS No.: 12036-44-1 Molecular Weight: 385.88 Density: 8.6 g/cm3 Melting point: 2341°C Appearance: White powder Solubility: Insoluble in water, moderately soluble in strong mineral acids Stability: Slightly hygroscopic Multilingual: ThuliumOxid, Oxyde De Thulium, Oxido Del Tulio Application 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. Thulium Oxide is used for making fluorescent materials, laser materials, glass ceramic additives. MThulium Oxide is used in the manufacturing of portable X-ray transmission devices, thulium is used as a radiation source for medical portable X-ray machines, and thulium is used as an activator LaOBr: Br (blue) in the fluorescent powder used for X-ray intensifying screens to enhance optical sensitivity, thereby reducing the exposure and harm of X-rays to humans; Thulium can also be used as a control material in metal halide lamps and nuclear reactors. Packaging: 50 kg/iron bucket, double layer plastic bag packaging inside; Or 50 kg/woven bag, packaged in double layer plastic bags; It can also be packaged according to customer requirements.
