Yttrium Oxide (Y2O3)-Sputtering Target

Characteristic

Yttrium oxide, also known as yttria, is Y₂O₃. It is an air-stable, white solid substance. Yttrium oxide is used as a common starting material for both materials science as well as inorganic compounds.

Molar mass： 225.81 g/mol

Appearance： White solid.

Density： 5.010 g/cm³, solid

Melting point： 2,425 °C (4,397 °F; 2,698 K)

Boiling point： 4,300 °C (7,770 °F; 4,570 K)

Solubility in water：insoluble

Solubility in alcohol：acid soluble

Crystal structure：Cubic (bixbyite)

Application

Yttria is widely used to make Eu:YVO₄ and Eu:Y₂O₃ 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 dopant allow the efficient operation both in continuous operation and in pulsed regimes.

Yttrium oxide is used to stabilize the Zirconia in late-generation porcelain-free metal-free dental ceramics. This is a very hard ceramic used as a strong base material in some full ceramic restorations.

Yttrium oxide is also used to make yttrium iron garnets, which are very effective microwave filters.
