Yttrium Oxide (Y2O3) Powder Properties

Y2O3-XRD

  • Insoluble in water and alcohol
  • Soluble in inorganic acids

Yttrium Oxide (Y2O3) Powder Applications

  • Y2O3 is widely used as an important material for tri-band rare earth phosphors that give the red color in color TV picture tubes.
  • Y2O3 is a prospective solid-state laser material. In particular, lasers with ytterbium as a dopant allow efficient operation both in continuous operation and in pulsed regimes.
  • Y2O3 is used to stabilize the Zirconia in late-generation porcelain-free metal-free dental ceramics. 
  • Y2O3 is also used to make yttrium iron garnets, which are very effective microwave filters.
  • Y2O3 is used in the manufacture of bricks, crucibles, and other high-temperature equipment.

Yttrium Oxide (Y2O3) Powder Storage and Packing

Yttrium Oxide (Y2O3) Powder should keep sealed and stored in a dry and cool place, avoiding being exposed to air for a long time. The vacuum-sealed packing is 100g/bag, 500g/bag, 1kg/bag, 25kg/drum, or as required.
