Yttrium chloride, with the chemical formula YCl3, is an important rare - earth chloride. It plays a significant role in the research and application of rare - earth materials.
Physical Properties
Anhydrous yttrium chloride is usually a white powdery solid, and the hexahydrate YCl3·6H2O is a colorless crystal.
The density of anhydrous yttrium chloride is approximately 2.98 g/cm³.
It has a melting point of about 721ºC and a boiling point of about 1507ºC.
Yttrium chloride is highly soluble in water and completely ionizes in water to form yttrium ions (Y³) and chloride ions (Cl). Its aqueous solution is weakly acidic due to the hydrolysis of yttrium ions.
It can form double salts with some alkali - metal chlorides, such as NaYCl4.
At high temperatures, yttrium chloride can react with some metal oxides to form the corresponding yttrium oxides.
Production Process
Usually, yttrium oxide (Y2O3) is used as the raw material and reacts with hydrochloric acid to prepare yttrium chloride. The chemical reaction equation is: Y2O3 + 6HCl = 2YCl3 + 3H2O.
Firstly, the yttrium - oxide powder is slowly added to the hydrochloric - acid solution of a certain concentration, and the reaction is carried out under stirring and appropriate heating to accelerate the reaction rate. After the reaction is completed, an aqueous solution of yttrium chloride is obtained.
Through operations such as evaporation, concentration, and cooling crystallization, the hydrate crystals of yttrium chloride can be obtained. To obtain anhydrous yttrium chloride, the hydrate needs to be heated in a hydrogen - chloride atmosphere to prevent hydrolysis, thereby obtaining high - purity anhydrous yttrium chloride.
Application Areas
Materials Science
It is used to prepare high - performance ceramic materials. Adding yttrium chloride to ceramics can improve the sintering properties, mechanical properties, and thermal stability of ceramics. For example, adding an appropriate amount of yttrium chloride to silicon - nitride ceramics can promote the densification of ceramics, improve their hardness and toughness, and make them widely used in aerospace, mechanical manufacturing, and other fields.
It is one of the important raw materials for preparing rare - earth permanent - magnet materials. In some rare - earth permanent - magnet alloys, the addition of yttrium chloride can adjust the crystal structure and magnetic properties of the alloy, improve the coercive force and maximum magnetic energy product of the permanent - magnet material, thereby enhancing the performance of the permanent - magnet material and being widely used in motors, electronic equipment, and other fields.
Optical Field
It can be used to manufacture optical glass and optical fibers. Adding yttrium chloride to optical glass can change the refractive index, dispersion, and other optical properties of the glass, improve the transparency and uniformity of the glass, and make it suitable for manufacturing high - quality optical lenses, prisms, and other optical components. In optical - fiber communication, yttrium chloride can be used as a dopant to improve the optical - transmission performance of optical fibers and enhance the efficiency and quality of signal transmission.
Catalytic Field
Yttrium chloride can be used as a catalyst or catalyst support for certain chemical reactions. For example, in some organic - synthesis reactions, such as esterification reactions and hydrogenation reactions, yttrium chloride can provide acidic centers or coordinate with reactants, thereby promoting the progress of the reaction and improving the selectivity and conversion rate of the reaction.
Medical Field
Radioactive yttrium chloride (such as yttrium chloride containing the radioactive isotope yttrium - 90) has certain applications in tumor treatment. It can release β - rays through the decay of radionuclides and perform close - range irradiation on tumor cells, thereby achieving the purpose of killing tumor cells and having potential application value in the radionuclide treatment of cancer.
Packaging and Storage
Packaging
The packaging of yttrium - chloride products is usually selected according to their purity and use. High - purity yttrium chloride for laboratory use is generally packaged in small packages, such as glass bottles or plastic bottles, with the content in each bottle ranging from a few grams to several tens of grams. Industrial - grade yttrium chloride is usually packaged in iron drums or plastic drums lined with plastic bags, with the weight in each drum generally being 25 kg or 50 kg.
Storage
It should be stored in a dry and well - ventilated warehouse to avoid moisture. It should be stored separately from oxidants, acids, and other substances to prevent chemical reactions. The storage area should be equipped with corresponding fire - fighting equipment and leakage - emergency - treatment equipment to ensure safety. For yttrium chloride containing radioactive isotopes, it also needs to be specially managed in accordance with the storage regulations for radioactive substances to ensure that the storage environment meets the radiation - protection requirements.
