Ytterbium(III) oxide

April 10, 2024

Ytterbium(III) oxide is the chemical compound with the formula Yb2O3. It is one of the more commonly encountered compounds of ytterbium. It occurs naturally in trace amounts in the mineral gadolinite. It was first isolated from this in 1878 by Jean Charles Galissard de Marignac.[3]

Preparation edit

Ytterbium(III) oxide can be obtained by directly reacting ytterbium with oxygen:[4]

4 Yb + 3 O2 → 2 Yb2O3

It can also be obtained by the thermal decomposition of ytterbium carbonate or ytterbium oxalate at temperatures around 700 °C:[5]

Yb2(CO3)3 → Yb2O3 + 3CO2
Yb2(C2O4)3 → Yb2O3 + 3 CO2 + 3CO

Properties edit

Chemical edit

Ytterbium(III) oxide is a white powder.[2] It reacts with carbon tetrachloride[6] or hot hydrochloric acid to form ytterbium(III) chloride:[7]

2 Yb2O3 + 3 CCl4 → 4 YbCl3 + 3 CO2
Yb2O3 + 6 HCl → 2 YbCl3 + 3 H2O

Physical edit

Like the other trivalent oxides of the heavier lanthanides, ytterbium(III) oxide has the "rare-earth C-type sesquioxide" structure which is related to the fluorite structure with one quarter of the anions removed, leading to ytterbium atoms in two different six coordinate (non-octahedral) environments.[8]
