Besides, it is a white fine powder, which should be stored in a cool and dry place.

Yttrium oxide is used as a common starting material for both materials science as well as inorganic compounds.
1. In materials science
Yttrium oxide is the most important yttrium compound and is widely used to make YVO₄ europium and Y₂O₃ europium 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. In inorganic synthesis
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.
3. In lasers
Y₂O₃ ceramics is a prospective solid-state laser material. In particular, lasers with ytterbium as dopant allow the efficient operation both in cw 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.

Physical properties about Yttrium oxide are: (1)#H bond acceptors: 3; (2)#Freely Rotating Bonds: 2; (3)Polar Surface Area: 43.37 Å².

Preparation: this chemical can be prepared by decomposition of yttrium niobium ore through extraction. Chemical reaction equation is as follows:
