'''Dysprosium(III) chloride''' (DyCl<sub>3</sub>), also known as '''dysprosium trichloride''', is a compound of ] and ]. It is a white to yellow solid which rapidly absorbs water on exposure to moist air to form a hexa], DyCl<sub>3</sub>·6H<sub>2</sub>O. Simple rapid heating of the hydrate causes partial ]<ref name="Edel">F. T. Edelmann, P. Poremba, in: ''Synthetic Methods of Organometallic and Inorganic Chemistry'', (W. A.

==Preparation and reactions== |
|
|
DyCl<sub>3</sub> is often prepared by the "] route", starting from either Dy<sub>2</sub>O<sub>3</sub> or the hydrated chloride DyCl<sub>3</sub>·6H<sub>2</sub>O.<ref> |

Dysprosium(III) chloride is a moderately strong ], which ranks as "hard" according to the ]. Aqueous solutions of dysprosium chloride can be used to prepare other dysprosium(III) compounds, for example dysprosium(III) fluoride: |

==Uses== |
|

Dysprosium(III) chloride can be used as a starting point for the preparation of other ] ]s. Dysprosium metal is produced when a molten mixture of DyCl<sub>3</sub> in ] ]-] is ].
