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 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 the air causes it to absorb carbon dioxide, which turns into dysprosium oxidate.

Dysprosium oxide

is the Main Use

Dysprosium dioxide can be used to make dysprosium and as an ingredient for glass and neodymium-iron boron permanent magnetics. 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. The past demand was low for dysprosium. But with NdFeB, this element is becoming a necessity. A magnet’s grade should 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 and neodymium-iron boron permanent magnetics.

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 and excitation peaks of the luminescent material powder are respectively 320nm & 365nm. 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.
