Structure and preparation method of gadolinium oxide Gd2O3 powder

Gadolinium oxide Gd2O3 powder overview

Gadolinium Oxide , the chemical formula is Gd2O3, using monazite or mixed rare earth ore as the raw material, after extraction and other purification steps, the samarium-gadolinium mixed rare earth solution is prepared, and the gadolinium oxalate is precipitated with oxalic acid. After separation, drying, and burning, Prepared gadolinium oxide. Preparation method: after extraction and other purification steps, a samarium-gadolinium mixed rare earth solution is prepared. Gadolinium oxalate is precipitated with oxalic acid, separated, dried, and burned to obtain gadolinium oxide.

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 symbol 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. Complications are 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.

Ga nano-particle gadolinium oxide Gd2O3 powder is a potential MRI contrast agent. At 7.05 T (compared to 0.5-3 T of clinical MRI scanner, abnormally high electric field), prepare 20-40 nm oxide g particles to coat deshosides, and the relaxation time of each particle is 4.8 s-1 mm-1, ion Smaller particles between 2 and 7 nm are tested as MRI reagents.
