Yttrium Oxide (Y₂O₃)

Yttrium Oxide, or Yttria, is the most thermodynamically stable compound in the oxide group. Its high-temperature stability makes it useful as a refractory material, as it has a thermal expansion that’s less than that of alumina, magnesia, and zirconia.
Various purities are available between 99.9% and 99.99%
Typical Applications

Y₂O₃ is used in numerous special applications such as
• Sintering additive for Si₃N₄, AlN, and SiC
• Stabilizer for Zirconias – e.g., YSZ coatings (TBCs); YSZ electrolytes for solid oxide fuel cells (SOFC)
• Catalyst carrier
• Luminescent materials (phosphors)
• Constituent of high-temperature superalloys and ODS materials
• Additive in special glass (Yttralox)
• Dopants for Barium Titanates in electroceramics

Packaging Options

50 lb. net in a sealed poly bag inside a plastic pail.
