General Information about Rare Earth Oxide-Yttrium Oxide Y2O3

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

Yttrium oxide  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).^[2] 

Yttrium oxide is an important starting point for inorganic compounds. For organometallic chemistry it is converted to YCl₃ in a reaction with concentrated hydrochloric acid and ammonium chloride.

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. At high concentration of excitations (of order of 1%) and poor cooling, the quenching of emission at laser frequency and avalanche broadband emission takes place.
