What’s dysprosium oxide?

Dysprosium Oxide

Dy2O3 chemical compound. The white powder is slightly hydrophobic and easily absorbs carbon dioxide from the atmosphere. It then turns into dysprosium carbate. Magnesium is stronger than high-iron oxide. Insoluble in acid and alcohol. Mainly used in lighting.

What are the effects of dysprosium dioxide?

It’s used to make dysprosium and as an ingredient in glass, neodymium iron-boron permanent magnets. It can be found in metal-halide lamps, magnetico-optical memory material, yttrium or yttrium aluminium garnet and other atomic energy industries. You can use dysprosium oxide as an additive to permanent magnets made of neodymium, iron-boron. The coercivity of a magnet may be increased by adding about 2 to 3.3% dysprosium. Dysprosium has been in high demand over the years. NdFeB makes it an essential element. The grade should be between 95 and 99.9%. Demand is increasing quickly. Also, dysprosium oxide can be used to make dysprosium metallic, an additive for glass and neodymium-iron boron permanent magnetics.

Introduction to Europium Oxide

Europium Oxide

This is a powder that is pale in color. The relative density is 7.42. The melting point of the material is at 22 degrees Celsius. Water insoluble, acid soluble. It can absorb water and carbon dioxide from the air.

How to make europium Oxide

The extraction method: Use rare earth chloride solutions obtained from processing monazite, mixed 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?

Prothrombin can be reduced by salts of rare Earth elements. They also inactivate prothrombin. The salt can precipitate fibrinogen or catalyze phosphoric acid compound decomposition. Toxicity of rare earth elements drops as their atomic weight rises. It is mandatory to use a gas mask while working. You should wear a gas mask if there’s radioactivity. You should prevent the dust scattering.

Europium Oxide, Dysprosium Oxide Storage

The container should be kept dry and cool in an enclosed place. It should not be subject to heavy pressure, and it should be transported in the same way as other ordinary objects.
