Ytterbium (III ) oxide is a chemical compound selected from the group of the oxides.
Occurrence
Ytterbium (III ) oxide occurs naturally in trace mineral Gadolinit. It was in 1878 by Jean Charles de Galissard Marignac from this isolated.
Production and representation
Ytterbium (III ) oxide can be obtained by reaction of ytterbium with oxygen.
It can also be obtained by thermal decomposition of ytterbium or Ytterbiumoxalat at temperatures around 700 ° C.
Properties
Ytterbium (III ) oxide is a white powder. Like the other trivalent oxides of the heavier lanthanides crystallize it in a cubic lanthanide - C structure. It reacts with carbon tetrachloride to hot hydrochloric acid or the ytterbium (III ) chloride.
Use
Ytterbium (III ) oxide is used as an additive for particular alloys and the dielectric ceramics, as a catalyst and in special glasses. It can also be used as an additive of carbon electrodes of the arc lamps that produce a very bright light.
