It is very stable in air, it reacts very slowly with oxygen and water and dissolves in acids.





Erbium is a soft, malleable, lustrous, silvery metal.

Erbium is not found free in nature but is found in a number of minerals: mainly monazite, bastnasite, xenotime and euxenite. Carl Mosander in 1843.





Jean Charles Galissard de Marignac Ytterbium was discovered by the Swiss chemist Jean Charles Galissard de Marignac in the year 1878.

The mineral gadolinite ( (Ce, La, Nd, Y) 2 FeBe 2 Si 2 O 10 ), discovered in a quarry near the town of Ytterby, Sweden, has been the source of a great number of rare earth elements. American Elements is a U.S. 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.



Its salts are rose coloured and it has a sharp adsorption spectra in visible, ultraviolet and infrared light.

Erbium is then isolated from the oxide or its salts by heating at 1450 For online linking, please copy and paste one of the following:To cite this page in an academic document, please use the following MLA compliant citation:This website uses cookies to improve your experience.

Discovered in Sweden, erbium is a lanthanide metal and a rare earth element. Discovered by the Swedish chemist, Carl Gustaf Mosander in 1843, erbium is one of the 17 rare earth elements.



Erbium was discovered by Carl Gustaf Mosander (SE) in 1843.





Dysprosium was discovered by Paul-Émile Lecoq de Boisbaudran, a French chemist, in 1886 as an impurity in erbia, the oxide of erbium.The metal was isolated by …



A lanthanide metal is a transition metal of the periodic table. Mosander was not certain of the purity of the oxides and l…

The metal itself is prepared by metallothermic reduction of the anhydrous fluoride with When raised to a high-energy state by absorption of

Erbium metal is used as alloyed with Vanadium to make it softer.





A modern analysis of gadolinite from this historically important mine gives extremely high concentrations for a number of rare earths: yttrium = 16% ; thulium = 5% ; ytterbium = 3%; terbium = 2% and …

These he called erbia and terbia; they contained the new rare earth metals erbium and The identities (and even the existence) of a number of rare earth elements was settled finally by George Urbain in Paris, who carried out tens of thousands of fractional crystallizations of rare earth salts.Crystallizations could take years to produce small samples of pure salts.Urbain finally put to rest uncertainty about the identities of pure earths whose salts had never before been completely free of other rare earth salts.Urbain found there were fifteen rare earth metals – we now recognize seventeen – one of which was erbium.

Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced.

In 1842.

Metal ignites and burns readily. Getting high purity research-quality rare-earth metals takes time. This turns the powder into a fluoride, such as the bright green praseodymium fluoride crystals (far right). Additionally, erbium Erbium has application in glass coloring, as an amplifier in fiber optics, and in lasers for medical and dental use. In 1842 Gustav Mosander separated "yttria", found in the mineral gadolinite, into three fractions which he called yttria, erbia, and terbia.

(The elements yttrium and ytterbium were also named after the same mine.)

In these fractions he found two differently colored, previously unknown substances.
It and the other rare earth elements …
