Dysprosium Chloride Hexahydrate Dycl3 CAS 15059-52-6 10025-74-8

Basic Information
Chemical Formula: DyCl3
English Name: Dysprosium Chloride
CAS Number: 10025-82-8 for anhydrous dysprosium chloride; 15059-52-6 for dysprosium chloride hexahydrate.
Appearance: Anhydrous dysprosium chloride is usually a white or slightly yellowish powder; dysprosium chloride hexahydrate is a colorless or light - yellow crystal.
Molecular Weight: Approximately 268.85 for anhydrous dysprosium chloride; approximately 376.95 for dysprosium chloride hexahydrate.

Physicochemical Properties
Density: The density of anhydrous dysprosium chloride is about 4.01 g/mL (25ºC).
Melting Point: The melting point of anhydrous dysprosium chloride is about 604ºC.
Solubility: It is soluble in water, and its aqueous solution is acidic. It is also soluble in organic solvents such as ethanol. Dysprosium chloride hexahydrate will gradually lose its crystal water when heated.

Preparation Method
It is generally prepared by the reaction of dysprosium hydroxide (Dy(OH)3) with hydrochloric acid. The reaction produces an aqueous solution of dysprosium chloride, and dysprosium chloride hexahydrate can be obtained through steps such as evaporation, concentration, and cooling crystallization. To prepare anhydrous dysprosium chloride, dysprosium chloride hexahydrate needs to be heated in a hydrogen chloride atmosphere to prevent hydrolysis.

Uses
Magnetic Materials: It is an important raw material for preparing high - performance magnetic materials. Adding dysprosium chloride to rare - earth permanent magnetic materials can improve the magnetic properties and performance of the materials, and it is widely used in the electronics and electrical fields.
Optical Field: It is used in the manufacture of optical glass, laser materials, etc. It can improve the refractive index and dispersion properties of optical materials, thereby improving the imaging quality and performance of optical devices.
Catalyst: It can be used as a catalyst in some organic synthesis reactions, which can improve the selectivity and efficiency of the reaction.
Scientific Research Field: As a rare - earth compound, it is often used in scientific research experiments to study the chemical and physical properties of rare - earth elements and the relevant reaction mechanisms.

Storage and Packaging
Storage: It should be stored in a sealed container, in a cool, dry, and well - ventilated place. Avoid dampness and contact with air to prevent it from absorbing moisture in the air and deliquescing.
Packaging: There are usually various packaging forms, such as vacuum packaging (common specifications are 1 kg, 5 kg, etc.), plastic bottle packaging (for small - dose products), cardboard drum packaging (generally 25 kg or 50 kg per drum), etc., to meet the needs of different users.
 

Packaging can be customized according to customer requirements.
