Thulium Oxide Micron Powder
Thulium oxide is a chemical compound which has chemical symbol Tm2O3. The melting point of Tm2O3 is nearly 2341℃ and has a density of 8.6 g/cm3. Thulium oxide (Tm2O3) powder appears in greenish-white color. Tm2O3 is insoluble in water while it is slightly soluble in acidic environments. Tm2O3 has a high dielectric constant of 12–13 and its energy band gap of 5 eV. These interesting properties have attracted attention in gate dielectric oxide applications or an interfacial layer to suppress the EOT growth during heat treatments. Tm2O3 micron powder can be prepared in the laboratory by burning thulium metal in air, or by decomposition of their oxoacid salts, such as thulium nitrate. Besides, Tm2O3 micron powders are generally used in the preparation of other terbium compounds due to its stability ,as an activation agent for fluorescent powders, in making of composite of CeO2-Tm4O7 used as catalytic automobile exhaust converters, as magneto-optical recording devices and magneto-optical glasses and making of glass materials for optical and laser-based devices.
