Information @ a Glance

General

  • Yttrium oxide is Y2O3. It is an air-stable, white substance.
  • Yttrium oxide is an important starting point for inorganic compounds.
  • Yttrium Oxide, also called Yttria, high purity Yttrium Oxides are the most important materials for tri-bands Rare Earth phosphors.
  • Yttrium occurs in nearly all of the rare-earth minerals.
  • Yttrium oxide is one of the most important compounds of yttrium and accounts for the largest use.

Synthesis

  • Yttrium oxide crystallized in cubic system and characterized by high thermoconductivity and transparence in the IR-range.
  • Nanoparticles of yttrium oxide formation were investigated using soft chemistry methods.
  • The yttrium oxide clusters are produced by laser ablation process.
  • Y2O3 nanoparticles have been synthesized by subambient homogeneous reduction using alkalide solutions and subsequent oxidation.

Application

  • Yttrium oxide is used to produce yttrium iron garnets which are useful microwave filters.
  • Yttrium oxide, Y2O3, is a medium-index, low-absorption material usable for coatings in the near-UV (300 nm) to IR (12 Ám) regions.
  • Yttria (Yttrium Oxide) has been used as a replacement by several manufacturers of leak detectors and ion gauge tubes.
  • Yttrium refines the martensitic lath structure of China Low Activation Martensitic (CLAM) steel and leads to the precipitation of big Y2Fe17C0.75 compound.

Technology

  • The sinterability of magnesium silicon nitride (MgSiN2) powder with yttrium oxide (Y2O3) addition was examined using the hot-pressing technique.
  • Deerac Fluidics Equator HTS eight tip pipetting system was used to pipette Yttrium Oxide SPA beads to 1536 well plates.
  • Europium-doped yttrium aluminum garnet ~YAG! particles were modified by the ultrasonic spray pyrolysis technoique of colloidal solutions.

Market

  • World production of rare earths is around 100,000 t/y rare earth oxide (REO). Output of yttrium is significantly less, of the order of 2,500 t/y yttrium oxide (Y2O3).
  • India is the second-largest source of yttrium, which is derived from its monazite production.
  • According to the news from the meeting, the Japanese market scale of rare earth has reached to about 30 billion and more than ten companies have engaged in the production and trade of rare earth.
