Character:
White or light yellow powder, with a density of 7.81g/cm3, a melting point of 2340 ℃, and a boiling point of about 4000 ℃. It is an ionic compound that is soluble in acids and ethanol, but not in alkali or water.
Applications:
Dysprosium oxide is used for neodymium iron boron permanent magnets as an additive . Adding about 2-3% of dysprosium to this type of magnet can improve its coercivity. In the past, the demand for dysprosium was not high, but with the increasing demand for neodymium iron boron magnets, it became a necessary additive element, with a grade of around 95-99.9%; As a fluorescent powder activator, trivalent dysprosium is a promising single emission center three primary color luminescent material activator ion. It is mainly composed of two emission bands, one is yellow light emission, and the other is blue light emission. Dysprosium doped luminescent materials can be used as three primary color fluorescent powders. Necessary metal raw materials for preparing large magnetostrictive alloy Terfenol, which can enable precise mechanical movements to be achieved; Used for measuring neutron spectra or as a neutron absorber in the atomic energy industry; It can also be used as a magnetic working substance for magnetic refrigeration.
It is used as raw material for producing dysprosium metal, dysprosium iron alloy, glass, metal halogen lamps, magneto-optical memory materials, yttrium iron or yttrium aluminum garnet, and control rods for nuclear reactors in the atomic energy industry.
