Gadolinium(III) nitrate hexahydrate
Overview
Gadolinium(III) nitrate hexahydrate is an inorganic compound primarily used in specialized industrial and research applications. It is a hydrated form of gadolinium nitrate, notable for its paramagnetic properties and role in advanced technologies. The compound is synthesized through the reaction of gadolinium oxide with nitric acid, followed by crystallization. Its hexahydrate form ensures stability under standard conditions, making it suitable for laboratory and industrial use.
Physical and Chemical Properties
This compound appears as colorless or white crystals and is highly soluble in water. Its hygroscopic nature requires careful storage to prevent moisture absorption. As an oxidizer, it poses fire risks when in contact with flammable materials. Gadolinium(III) nitrate hexahydrate exhibits paramagnetic behavior due to the presence of gadolinium ions, which is exploited in applications like MRI contrast agents. It decomposes upon heating, releasing nitrogen oxides and water vapor.
Main Applications
The compound is widely used in catalysis, particularly in organic synthesis and petroleum refining. Its neutron-absorbing properties make it valuable in nuclear reactors and radiation shielding. In medical imaging, gadolinium-based contrast agents derived from this compound enhance MRI scans. Research laboratories also utilize it for studying rare-earth chemistry and material science.
Safety and Storage
Due to its oxidizing nature, Gadolinium(III) nitrate hexahydrate must be stored away from reducing agents and organic materials. Proper ventilation and PPE, including gloves and goggles, are essential during handling. Long-term storage should be in airtight containers with desiccants to prevent hydration. Spills should be neutralized with appropriate absorbents and disposed of according to local regulations.
B2B Procurement Guide
When sourcing Gadolinium(III) nitrate hexahydrate, prioritize suppliers with ISO certification and proven track records. Specify required purity levels (e.g., 99.9% for research-grade applications). Bulk purchases often reduce costs, but ensure proper storage capacity. Request material safety data sheets (MSDS) and certificates of analysis (CoA) to verify quality and compliance.
