Properties
Physical Properties: Gadolinium nitrate hexahydrate is a colorless or white crystalline powder. It is highly soluble in water, forming a colorless solution, and is also soluble in organic solvents such as ethanol. It is deliquescent.
Chemical Properties: It has the typical properties of nitrates. It decomposes when heated to form gadolinium oxide, nitrogen oxides, and oxygen. It can react with alkalis to form gadolinium hydroxide precipitate and can form complexes with some ligands.
Production Process
Usually, it is prepared by reacting gadolinium oxide with nitric acid. The reaction equation is:
Gd2O3+6HNO3+3H2O=2Gd(NO3) 3⋅6H2O.
Specifically, gadolinium oxide is added to an appropriate amount of nitric acid solution, and the reaction is carried out under certain temperature and stirring conditions to fully dissolve gadolinium oxide. After the reaction is completed, the gadolinium nitrate product is obtained through steps such as evaporation and concentration, cooling and crystallization, filtration, and drying.
Application Areas
Medical Field: Gadolinium nitrate is an important raw material for the preparation of magnetic resonance imaging (MRI) contrast agents. Gadolinium ions are paramagnetic and can shorten the relaxation time of surrounding water molecules, thereby enhancing the contrast of tissues and helping doctors observe the internal lesions of the human body more clearly.
Optical Materials: It can be used to prepare optical materials such as optical glass and laser crystals, which can improve the optical properties of materials, such as refractive index and transmittance.
Catalysts: It can be used as a catalyst or a component of a catalyst in some chemical reactions to increase the reaction rate and selectivity. For example, it plays a role in some organic synthesis reactions.
Packaging and Storage
Packaging: Generally, it is packaged in a sealed manner, such as in plastic or glass bottles, and then repackaged in sealed bags or cans to prevent the product from absorbing moisture and coming into contact with air.
Storage: It should be stored in a cool, dry, and well - ventilated warehouse, away from fire sources and heat sources. Avoid mixing it with flammable substances, reducing agents, acids, and other substances to prevent chemical reactions. At the same time, pay attention to moisture - proof and regularly check whether the packaging is intact to ensure the product quality.
