Physicochemical properties and preparation of dysprosium oxide

Dysprosium oxide is a chemical substance with the chemical formula Dy₂O₃. White powder, slightly hygroscopic, can absorb moisture and carbon dioxide in the air. Magnetism is many times stronger than ferric oxide. Soluble in acid and ethanol. Mainly used for lighting sources.

Dysprosium oxide physical and chemical data

The relative molecular mass is 373.00, and the relative density (d274) is 7.81. Melting point 2340±10℃. Boiling point 3900 ℃.

Physicochemical properties and preparation of dysprosium oxide

White crystalline powder, insoluble in water, soluble in acid and ethanol. When exposed to air, it is easy to absorb carbon dioxide and turn into dysprosium carbonate.

Preparation of dysprosium oxide

Dysprosium nitrate solution reacts with sodium hydroxide solution to generate dysprosium hydroxide, which is calcined after separation to obtain dysprosium oxide:

2Dy(OH)₃═Δ═Dy₂O₃+3H₂O

Dysprosium oxide Dy2O3 overview

Dysprosium oxide Dy2O3 is white powder, slightly hygroscopic, and can absorb moisture and carbon dioxide in the air. Magnetism is many times stronger than high iron oxide. Soluble in acid and ethanol. Mainly used for light sources.

The relative molecular weight of dysprosium oxide Dy2O3 is 373.00, and the relative density (D274) is 7.81. Melting point is 2340 plus or minus 10°C. The boiling point is 3900°C.

The nuclear power industry uses nuclear reactor control rods. Magnetic material. Comprehensive utilization.

It is a pale yellow to pale green, slightly hygroscopic powdery powder designed for use in ceramic, glass, phosphor, laser and bimetal halide lamps. It can react with acids to form the corresponding (III) salts:

Dy2O3 + 6HCl→2DyCl3 + 3H2O

When the oxidized dysprosium is exposed to the air and becomes carbonic acid, the dew easily absorbs the carbon dioxide.

Application of dysprosium oxide

Dysprosium oxide is used as metal raw material, glass additive and NdFeB permanent magnet.

Dysprosium oxide Dy2O3 is used in metal halide lamps, magneto-optical storage materials, yttrium iron or yttrium aluminum garnet, and the atomic energy industry.

Adding about 2 to 3 percent to this magnet can increase its awareness. In the past, the demand for dy was not large, but with the increase in demand for NdFeB, it has become a necessary additive element, with a grade of about 95-99.9%, and the demand is also growing rapidly.
