Overview of Gadolinium Oxide Gd2O3 Powder:
Gadolinium oxide Gd2O3 powder is an inorganic compound with the molecular formula Gd2O3. It is one of the most common forms of rare earth element g, and its derivatives are potential magnetic resonance imaging contrast agents.
The oxide of Gadolinium Oxide Gd2O3 powder has two structures. The cubic (CI80, IA3, No.206) structure is similar to manganese (III) oxide and heavy trivalent lanthanide sesquioxide. There are two types of sites in the cubic structure. The coordination number of each site is 6, but the coordination geometry is different. The second form is monoclinic (Pearson notation MS30, space group C2/M, number 12). At room temperature, the cubic structure is more stable. This phase becomes monoclinic at 1200°C. The melting point is higher than 2100℃～2420℃, mainly hexagonal phase.
Gadolinium oxide Gd2O3 powder can be formed by the thermal decomposition of hydroxide, nitrate, carbonate or oxalate. Oxidation d is formed on the surface of metal g.
Gadolinium oxide Gd2O3 powder is a strong alkaline oxide that can react with carbon dioxide to form carbonate. Easily soluble in common inorganic acids. The complication is that oxalic acid, fluoride, sulfate, and phosphate are extremely difficult to dissolve in water and may cover oxide particles, preventing them from dissolving completely. At present, there are many methods for synthesizing oxide nanoparticles, mainly by reacting ionic ions with hydroxide to precipitate hydroxide, and then performing thermal dehydration to obtain oxide g. Nanoparticles are always coated with protective materials to prevent the formation of larger polycrystalline aggregates.
Gadolinium oxide Gd2O3 powder of Ga nanoparticles is a potential MRI contrast agent. At 7.05 T (compared to the 0.5-3 T of clinical MRI scanners, an abnormally high electric field), 20-40 nm oxide g particles were prepared to coat deshosides, and the relaxation time of each particle was 4.8 s-1 mm -1, smaller particles with ions between 2 and 7 nm are tested as MRI reagents.
