Dysprosium Chloride (DyCl3)-Powder

Characteristic

Dysprosium(III) chloride (DyCl₃), also known as dysprosium trichloride, is a compound of dysprosium and chlorine. It is a white to yellow solid which rapidly absorbs water on exposure to moist air to form a hexahydrate, DyCl₃.6H₂O.

Chemical formula：DyCl₃

Molar mass： 268.86 g/mol (anhydrous)

Appearance： white solid

Density： 3.67 g/cm³, solid

Melting point： 647 °C (1,197 °F; 920 K) (anhydrous)

Boiling point： 1,530 °C (2,790 °F; 1,800 K)

Solubility in water：Soluble

Crystal structure：AlCl₃ structure

Application

Dysprosium(III) chloride can be used as a starting point for the preparation of other dysprosium salts. Dysprosium metal is produced when a molten mixture of DyCl₃ in eutectic LiCl-KCl is electrolysed. The reduction occurs via Dy²⁺, at a tungsten cathode.
