What’s Dysprosium Oxide?

Dysprosium Oxide is a chemical substance that has the chemical formula Dy2O3. The white powder is slightly hydrophobic and can absorb water as well as carbon dioxide from the air. Magnesium is stronger than that of high iron oxide. Insoluble in acid and alcohol. Mainly used in lighting.

Dysprosium oxide

1. Chemical and physical data

The relative molecular masses of dysprosium dioxide are 373.00 and (d274) 8.81 respectively. The melting point for the material is approximately 234010°C. The boiling point for the substance is around 3900°C.

2. Property of physical and chemical substances

Dysprosiumoxide is a white crystal powder. It’s insoluble when water is used, but can be dissolved in acid or ethanol. Exposure to air causes it to absorb carbon dioxide, which turns into dysprosium carbate.

Dysprosium oxide

is the Main Use

Dysprosium dioxide can be used as raw material to make dysprosium and as an additive for glass and neodymium-iron boron magnets. Also used in magnetooptical memory materials and metal halide lamp, metal halide and magneto-optical lamps. As an additive for permanent magnets made of neodymium iron-boron, dysprosium can be also used. The coercivity of a magnet may be increased by adding about 2 to 3.3% dysprosium. Although the market for dysprosium has been small in the past due to its low demand, this is changing with NdFeB. The grade must be between 95 and 99.9%. This demand is growing rapidly. Also, dysprosium oxide can be used to make dysprosium metallic, an additive for glass, Neodymium Iron Boron permanent magnets and in magneto-optical memories materials.

Prepare Dysprosium Oxide-Luminescent Material

You will need to weigh the correct amount of Europium Oxide and Dyprosium Oxide powder. After preparing ionic Solution A, heat and stir. Finally, you can add to solution B by heating and stirring. The solution is ready to be used once it’s evaporated at 80°C. You quickly transfer the solution to the corundum container and seal it. The high-temperature resistance furnace can be preheated up to 600°C. Next, place the container containing the precursor solution in the furnace and quickly close the door. Once heated, the precursor solution instantly boils and produces large amounts of heat. It takes approximately 5 minutes to complete the entire process. Once the sample has been removed, it can be cooled at room temp.

It is a porous, loosely porous product that has a yellowish-green color. You can grind the product into SrAl2O4;Eu2+ and Dy3+ luminescent material. The initial illuminance is 15lux, with an additional 12h afterglow. The emission peak is 510nm. When the particle size is greater than a nanometer, it is possible for the relative Eu and Dy levels to change or destroy the crystal lattice. The luminous brightness of the luminescent material is decreased or no light is emitted. But if the particle size is too big, this can cause uneven coating films or a sloppy appearance. This test shows that the luminescent dust has a particle size greater than 75mm.
