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 µm) 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.
