CAS:10025-75-9
Molecular formula: ErCl3·6H2O
Molecular weight:381.71
EINECS:233-385-0
Erbium chloride is an important rare - earth compound with the chemical formula ErCl3, which is widely used in various fields.
Physical Properties
Anhydrous erbium chloride is a white or slightly pinkish powder, while erbium chloride hexahydrate is a pink crystal. It has a bright color and a certain luster.
The density of anhydrous erbium chloride is about 3.86 g/mL (25ºC). It has a relatively high density, which is related to its crystal structure and atomic composition.
The melting point of anhydrous erbium chloride is about 774ºC. It can exist stably at high temperatures and has high thermal stability.
Erbium chloride is highly soluble in water and can be completely ionized in water to form erbium ions and chloride ions. Its aqueous solution is acidic. This is because erbium ions will undergo hydrolysis reactions in water, increasing the concentration of hydrogen ions in the solution.
It is soluble in organic solvents such as ethanol. This property makes erbium chloride more applicable in the fields of organic synthesis and material preparation.
Erbium chloride hexahydrate will gradually lose its crystal water when heated. It will form different hydrates at different temperature stages, and finally, anhydrous erbium chloride can be obtained at high temperatures.
Production Process
Erbium chloride is usually prepared by the reaction of erbium hydroxide (Er(OH)3) with hydrochloric acid. Erbium hydroxide is slowly added to an appropriate amount of hydrochloric acid to carry out a neutralization reaction: Er(OH)3 + 3HCl = ErCl3 + 3H2O. After the reaction is completed, an erbium chloride solution is obtained.
The erbium chloride solution is evaporated and concentrated to make the solution supersaturated, and then cooled and crystallized to obtain erbium chloride hexahydrate crystals.
To obtain anhydrous erbium chloride, erbium chloride hexahydrate needs to be heated and dehydrated in a hydrogen chloride atmosphere. This is because under normal heating conditions, erbium chloride will undergo a hydrolysis reaction to form erbium hydroxide or erbium oxide. However, in a hydrogen chloride atmosphere, the hydrolysis reaction can be inhibited, and thus anhydrous erbium chloride can be obtained.
Application Fields
Optical Field
In optical fiber communication, erbium chloride is a key raw material for manufacturing erbium - doped fiber amplifiers (EDFAs). EDFAs can directly amplify optical signals, greatly improving the transmission distance and quality of optical signals. They are important components indispensable in modern optical fiber communication systems.
It is used in the preparation of optical glass, which can improve the optical properties of glass, such as increasing the refractive index and reducing the dispersion. This improves the imaging quality and optical performance of optical glass and is widely used in optical instruments such as telescopes, microscopes, and camera lenses.
It is an important component of laser materials and can be used to manufacture solid - state lasers. Erbium ions can generate laser light of specific wavelengths in the laser medium, which has important applications in scientific research, medicine, industrial processing, and other fields.
Magnetic Materials Field
In the research and development of magnetic materials, erbium chloride is often used as an additive. It can adjust the magnetic properties of materials, such as the Curie temperature and magnetic permeability, which helps to prepare high - performance magnetic materials. These magnetic materials are widely used in electronic equipment, power transmission, sensors, and other fields.
For example, in some new permanent magnetic materials, adding an appropriate amount of erbium chloride can improve the crystal structure and magnetic domain structure of the materials, enhance the permanent magnetic properties of the materials, and make them have higher remanence, coercive force, and maximum magnetic energy product, thus meeting the high - performance requirements of magnetic materials in different application scenarios.
Catalyst Field
In organic synthesis reactions, erbium chloride can play an important role as a catalyst. It can participate in the reaction mechanism and affect the reaction rate and selectivity by interacting with reactant molecules, changing the activation energy and reaction path of the reaction.
For example, in some esterification reactions, alkylation reactions, and isomerization reactions, the erbium chloride catalyst can improve the reaction efficiency, make the reaction proceed under milder conditions, and reduce the occurrence of side reactions, thereby improving the purity and yield of the product.
Medical Field
In medical research and diagnosis, erbium chloride has potential application value. Erbium ions have unique optical and magnetic properties and can be used in medical imaging technologies such as magnetic resonance imaging (MRI) and optical imaging.
By labeling erbium chloride on biomolecules or cells, the imaging and tracking of specific tissues or cells in the body can be achieved, which helps doctors more accurately diagnose diseases, study the occurrence and development mechanism of diseases, and monitor the effect of drug treatment.
Packaging and Storage
Packaging
Erbium chloride products usually adopt a variety of packaging forms to meet the needs of different users. Common packaging includes vacuum packaging, with specifications of 1 kg, 5 kg, etc., which is suitable for users with high requirements for product purity and storage conditions. Plastic bottle packaging is generally used for the packaging of small - dose products, which is convenient for use in laboratories or research institutions. Cardboard drum packaging, with common specifications of 25 kg or 50 kg, is suitable for large - scale procurement and use by industrial users.
Storage
Erbium chloride should be sealed and stored in a cool, dry, and well - ventilated place. Since erbium chloride is prone to absorbing water and deliquescing, it should be kept away from air and moisture to prevent the product from deteriorating. At the same time, it should be kept away from fire sources and flammable materials to avoid fires or other safety accidents. During the storage process, the packaging should be regularly inspected for integrity. If there is any damage or leakage, it should be dealt with in a timely manner.
