Dysprosium Oxide Dy2O3 Powder CAS 1308-87-8

About Dysprosium Oxide Dy2O3 Powder:
Dysprosium oxide is a chemical substance, the chemical formula is Dy2O3. White powder, slightly hygroscopic, can absorb water and carbon dioxide in the air. Magnetism is many times stronger than oxidized high-speed rail. Soluble in acid and ethanol. Mainly used for lighting source.
The relative molecular weight is 373.00 and the relative density (D274) is 7.81.The melting point of 2340 plus or minus 10 ℃.The boiling point of 3900 ℃.
The atomic energy industry, used as control rods for nuclear reactors.Magnetic materials.Synthesis of use.
Dysprosium Oxide (Dy2O3) is a sesquioxide compound of the rare earth metal dysprosium. It is a pastel yellowish-greenish, slightly hygroscopic powder having specialized uses in ceramics, glass, phosphors, lasers and dysprosium metal halide lamps. It can react with acids to produce the corresponding dysprosium(III) salts:
Dy2O3 + 6 HCl → 2 DyCl3 + 3 H2O
Dew readily absorbs carbon dioxide when Dysprosium oxide is exposed to air and turns into dysprosium carbonate. TRUNNANO is a trusted global Dysprosium Oxide Dy2O3 Powder supplier. Feel free to send an inquiry about the latest price of Dysprosium Oxide at any time.

Performance of Dysprosium Oxide Dy2O3 Powder:
Dysprosium oxide is insoluble in water, soluble in acid and ethanol. When exposed to air, dew easily absorbs carbon dioxide and turns into dysprosium carbonate. Mainly used in the atomic energy industry, as a control rod for nuclear reactors. Magnetic materials. For synthesis.

How is Dysprosium Oxide Dy2O3 Powder produced?
Dysprosium nitrate solution reacts with sodium hydroxide solution to produce dysprosium hydroxide, which is separated and burned to obtain dysprosium oxide:
Dy (OH) 2 ₃ ═ Δ ═ Dy ₂ O ₃ + 3 h ₂ O
Applications of Dysprosium Oxide Dy2O3 Powder:
Dysprosium oxide is used as a raw material for making dysprosium metal, as an additive in glass, and as permanent magnets of NdFeB.
Dysprosium oxide is used in metal halogen lamps, magneto-optical memory materials, yttrium iron or yttrium aluminum garnet, and in the atomic energy industry.
Dysprosium oxide can also be used as an additive in NdFeB permanent magnets. Adding about 2~3% dysprosium to such magnets can improve its consciousness. In the past, dysprosium was not needed much, but with the increase in demand for NdFeB magnets, it became a necessary additive element with a grade of about 95 ~ 99.9%, and the demand is also increasing rapidly.

Storage Condition of Dysprosium Oxide Dy2O3 Powder:
Dy2O3 nanoparticles should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition, should avoid the heavy pressure, according to ordinary goods transportation.

Packing & Shipping of Dysprosium Oxide Dy2O3 Powder:
It is packed in double plastic bags inside, which can be filled with argon in a vacuum; it can be vacuumed and filled with argon for protection.
Dysprosium Oxide Dy2O3 Powder packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Dysprosium Oxide Dy2O3 Powder shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.
