Herstellung & Synthese
synthetische
Europium Chloride, EuCl3, is formed as fine yellow needles by heating the hydrated chloride in a mixture of chlorine and sulphur monochloride. Europium chloride was prepared by dissolving Europium(III) oxide in excessive 6 mol/L HC1, then hydrated europium chloride was obtained by evaporating away excess HC1 from the solution.
