Product Description
English: Oxide Dysprosium
Molecular formula: Dy2O3
Molecular weight: 373.02
CAS: 1308-87-8
Packing: 10, 25, 50 kg / bag, two layer plastic bags, woven, drums, drum or plastic drum. 
Character
White or light yellow powder, density 7.81g/cm3, melting point of 2340 degrees Celsius, the boiling point is about 4000 degrees Celsius, for ionic compounds, soluble with acid and ethanol, but not soluble in alkali, also not soluble in water. 
Application domain: 
Improve the coercivity can be used as neodymium iron boron permanent magnet additives, in the magnet added about 2-3% of dysprosium, past dy the demand for small, but with the increase of neodymium iron boron magnet demand, it becomes necessary to add elements, the grade should be in 95 to 99.9%; Used as phosphor activators and trivalent dysprosium is a promising single luminescence center three color luminescent material activated ion, which is mainly composed of a two emission band composed, a yellow light emission, another blue emission, dysprosium doped luminescent materials can as tricolor fluorescent powder. For preparation of giant magnetostrictive alloy TB dy Fe alloy (Terfenol) necessary metal raw material, can make some mechanical motion precision activities to be implemented; Used in the atomic energy industry in the determination of the neutron energy spectrum and neutron absorber; It also can be used magnetic cold with magnetic materil.

Property description: 
Products should be white crystals. Product clean, no obvious mechanical inclusions. 
Packing: 1000 kg ton bag. 
Product application: 
1 used in the manufacture of special alloy precision optical glass, high refractive index optical fiber board, suitable for camera, camera, microscope lens and advanced optical instrument prism, etc. ., 
2 used in the manufacture of ceramic capacitors, piezoelectric ceramic doped agent and X - ray luminescent materials, such as lanthanum bromide. 
3 used as a catalyst for a variety of reactions, such as the oxidation of carbon monoxide when doped with cadmium oxide reaction, the reaction of carbon monoxide hydrogenation to produce methane. 
4 impregnated lithium oxide or zirconium oxide (1%) lanthanum oxide can be used in the manufacture of ferrite magnets. 
5 is a very effective selective catalyst for the oxidative coupling of methane to ethylene and ethylene. 
6 for improving the temperature dependence and dielectric properties of barium titanate (BaTiO3), strontium titanate (SrTiO3) ferroelectric, and the fabrication of fiber optic devices and optical glass. 
Preparation method: 
Carbonate precipitation method to the extraction separation of lanthanum chloride solution as raw materials, ammonium bicarbonate and precipitation of lanthanum carbonate, by heating, aging, washing, separation, and burning of lanthanum oxide. Can be prepared by heating the decomposition of lanthanum oxalate.
