What’s Dysprosium Oxide? Dysprosium Oxide is a chemical substance that has the chemical formula Dy2O3. The white powder is somewhat hygroscopic and can absorb water and carbon dioxide from the air. Magnesium is stronger than that of high iron oxide. Insoluble in acids and ethanol. Primarily used in lighting.
Dysprosium oxide
1. Chemical and physical dataThe 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 air causes it to absorb carbon dioxide, which turns it into dysprosium or carbonate.Dysprosium oxide
is the Main Use As an ingredient in the production of dysprosium alloy, it can be used to make glass and neodymium-iron boron magnets. Dysprosium is also used in magnetooptical memory materials and metal halide lamp, as well as in yttrium or yttrium aluminium garnet and other atomic energy industries. 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 of the magnet 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 and neodymium-iron boron permanent magnetics.Prepare Dysprosium Oxide-Luminescent Material
You will need to weigh appropriate quantities 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. 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 luminescent particles reach a nanometer size, either the relative Eu or Dy content changes or the crystall lattice becomes destroyed, the brightness of the light can be reduced or zero. But if the particle sizes of luminescent are too large, this will make the coating film unevenly or not smooth. This test shows that the particle size for luminescent dust is greater than 75mm.
