Description
Dysprosium Oxide Product Overview
Dysprosium oxide (Dy2O3) is a greenish-white to pale yellow powder that is insoluble in water but dissolves in acids. It is strongly paramagnetic and absorbs moisture and carbon dioxide slowly from the air.
The most important use is as the raw material for dysprosium metal. Adding dysprosium to neodymium-iron-boron magnets raises their coercivity at high temperatures, which is essential for motors in electric vehicles and wind turbines. It is also used in the magnetostrictive alloy Terfenol-D, often together with Terbium Oxide.
Dysprosium oxide also serves as a dopant in multilayer ceramic capacitors, in phosphors and metal halide lamps, and in nuclear control materials because of its high neutron absorption. Related rare earth materials include Neodymium(III) nitrate hexahydrate, Gadolinium Oxide and Lanthanum Oxide.
