What is the dysprosium oxid? Dysprosium oxide Dy2O3 has the chemical compound Dy2O3. The white powder, which is slightly hygroscopic absorbs carbon dioxide easily when exposed to air. It turns into dysprosium acetate. Magnetism can be many times more powerful than high iron oxide. It is soluble in acid and ethanol. Mostly used in lighting sources.
What are the effects of dysprosium Oxide?
It is also used in the production of neodymium, iron boron and glass permanent magnets. Also, it is used for atomic energy, metal halide, magneto-optical materials, yttrium or yttrium aluminium garnets, and magneto-optical memories. As an additive to neodymium, iron-boron permanent magnetic materials, dysprosium oxide is also available. Adding 2 to 3 percent of dysprosium will increase the magnet’s coercivity. Dysprosium oxide was previously not in high demand, but now it is a vital element for NdFeB magnets. Its grade must also be between 95 and 99.9%. Dysprosium Oxide is also used to prepare dysprosium metallic, as an addition for glass, for neodymium ferroboron permanent magnetic materials, for yttrium or yttrium-aluminum garnet and in the atomic energy industry.

Introduction to Europium Oxide
Europium Oxide This powder is pale red. The relative densities is 7.42. The melting temperature is 2002 degrees. Insoluble in acid, but soluble with water. It can absorb both carbon dioxide and water from the air.

How to make the europium dioxide
Extraction Method: Take the solution of rare earth chloride, obtained by processing mixed or monazite rare earth ore. Extraction with P204-kerosene-HCL-ReCl3 system, the first grouping of neodymium and samarium, the raffinate is used to extract light rare earth, samarium and heavy rare earth are extracted into the organic phase, and then the middle rare earth are back-extracted with 2.0mg/L HCl to obtain a medium After the rare earth samarium enrichment is reduced by zinc powder, europium is extracted by the alkalinity method and then precipitated with oxalic acid, separated, dried, and burned to obtain europium oxide.

Is europium oxide toxic?
The salt of rare Earth elements can inhibit the production and reduce the content of thrombin. It can also precipitate fibrinogen. As atomic weight increases, the toxicity decreases. Gas masks are required to be worn when you work. Radioactivity requires special protection. It is important to prevent dust from spreading.

Storage of Dysprosium Oxide and Europium Oxide
The product should be kept in a sealed, dry, cool environment and not exposed. Additionally, it is best to avoid using heavy pressure when transporting the item.
