What is the dysprosium oxid? Dysprosium oxide Dy2O3 has the chemical compound Dy2O3 as its formula. The white powder is slightly hygroscopic. It absorbs carbon dioxide easily when exposed to air. 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?
As an additive to glass, neodymium ferroboron permanent magnets and dysprosium as a raw material. Also, it is used for yttrium-iron or yttrium-aluminum garnets, metal halide lamp, magnetooptical memory material, and the atomic energy industry. Dysprosium can be added to neodymium, iron and boron permanent magnetic materials. Adding 2 to 3 percent of dysprosium will increase the magnet’s coercivity. Previously, dysprosium wasn’t in high demand, but now that magnets are more popular, the element is a must-have. Its grade needs to be between 95 and 99.9%. Dysprosium Oxide is used as a source for dysprosium and as an additive in neodymium-iron-boron permanent magnets. It can also be used for metal halide lights, magnetooptical memory materials and yttrium or yttrium aluminium garnet.

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 of fibrinogen and reduce the content of Prothrombin. It also precipitates fibrinogen and catalyzes the decomposition phosphoric acids compounds. The toxicity decreases with increasing atomic weight. Gas masks are required to be worn when working. Radioactivity requires special protection. It is important to prevent dust from spreading.

Store Europium Oxide & Dysprosium Oxide
The product should be kept in a sealed, cool, and dry environment. It shouldn’t be exposed to the atmosphere. Also, it is best to avoid using heavy pressure when transporting the item.
