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.
Chemical formula：Y2O3
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.
