Erbium is a chemical element; it has symbol Er and atomic number 68. A silvery-white solid metal when artificially isolated, natural erbium is always found in ...
Erbium(III) chloride is a violet compounds that can be formed by first heating erbium(III) oxide and ammonium chloride to produce the ammonium salt of the pentachloride ([NH 4] 2 ErCl 5) then heating it in a vacuum at 350-400 °C.

Erbium(III) telluride is an inorganic compound, one of the tellurides of erbium, with the chemical formula Er 2 Te 3. It has a Sc 2 S 3 structure, a space group of Fddd, a band gap of 0.77(5) eV, and semiconducting properties. [1] It can be obtained by the reaction of erbium and tellurium [2] [3] or the chemical vapor transport of erbium(III ...
Erbium(III) chloride forms crystals of the AlCl 3 type, with monoclinic crystals and the point group C2/m. [2] Erbium(III) chloride hexahydrate also forms monoclinic crystals with the point group of P2/n (P2/c) - C 4 2h. In this compound, erbium is octa-coordinated to form [Er(H 2 O) 6 Cl 2] + ions with the isolated Cl − completing the ...
Yttrium, erbium, and terbium are all named after the village of Ytterby in Sweden. [47] [48] Terbium was not isolated in pure form until the advent of ion exchange techniques. [49] Mosander first separated yttria into three fractions, all named for the ore: yttria, erbia, and terbia.
Erbium nitride is a binary inorganic compound of erbium and nitrogen with the chemical formula ErN. [1] Physical properties. The compound forms black powder ...
Erbium(III) selenate octahydrate is first dehydrated by heating to obtain the anhydrous form, and then heated continuously to obtain erbium selenite and finally erbium(III) oxide. [1] [2] It can crystallize with M 2 SeO 4 in aqueous solution to form double salts, such as K 3 Er(SeO 4) 3 ·nH 2 O [3] and NH 4 Er(SeO 4) 2 ·3H 2 O, [4] etc.
