ytterbia

Marignac suspected that ytterbia was a compound of a new element that he called "ytterbium".

All of these men found lutetium as an impurity in the mineral ytterbia, which was previously thought to consist entirely of ytterbium.

In 1907, the French chemist Georges Urbain separated Marignac's ytterbia into two components: neoytterbia and lutecia.

They found it as an impurity in ytterbia, which was thought by Swiss chemist Jean Charles Galissard de Marignac to consist entirely of ytterbium.

He suspected that ytterbia was a compound of a new element that he called "ytterbium" (in total, four elements were named after the village, the others being yttrium, terbium and erbium).

In 1907, the new earth "lutecia" was separated from ytterbia, from which the element "lutecium" (now lutetium) was extracted by Georges Urbain, Carl Auer von Welsbach, and Charles James.

The ytterbium(III) ion absorbs light in the near infrared range of wavelengths, but not in visible light, so the mineral ytterbia, YbO, is white in color and the salts of ytterbium are also colorless.

While examining samples of gadolinite, Marignac found a new component in the earth then known as erbia, and he named it ytterbia, for Ytterby, the Swedish village near where he found the new component of erbium.

In 1878, the Swiss chemist Jean Charles Galissard de Marignac separated in the rare earth "erbia" another independent component, which he called "ytterbia", for Ytterby, the village in Sweden near where he found the new component of erbium.

The Austrian chemist Carl Auer von Welsbach independently isolated these elements from ytterbia at about the same time, but he called them aldebaranium and cassiopeium; the American chemist Charles James also independently isolated these elements at about the same time.
