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.

It is the most important yttrium compound and is widely used to make Eu:YVO4 and Eu:Y2O3 phosphors that give the red color in color TV picture tubes.
Yttrium oxide is also used to make yttrium iron garnets, which are very effective microwave filters.

Y2O3 is used to make the high temperature superconductor YBa2Cu3O7, known as "1-2-3" to indicate the ratio of the metal constituents:

2 Y2O3 + 8 BaO + 12 CuO + O2 → 4 YBa2Cu3O7

This synthesis is typically conducted at 800 °C.
The thermal conductivity of yttrium oxide is 27 W/(m·K)
