About Gadolinium Oxide Gd2O3 Powder:
Gadolinium oxide is an inorganic compound with the molecular formula Gd2O3. It is one of the most common forms of the rare earth element gadolinium, a derivative of which is a potential magnetic resonance imaging contrast agent.
Gadolinium oxide has two structures. Cubic (CI80, IA3), No.206) structures are similar to manganese (III) oxides and heavy trivalent lanthanide sesquioxides. The cubic structure has two types of gadolinium sites, each with a coordination number of 6, but with different coordination geometry. The second form is monoclinic (Pearson symbol MS30, space group C2/ M, number 12). At room temperature, the cubic structure is more stable. The phase changes into the monoclinic structure at 1200°C. Above 2100℃ to 2420℃ melting point, mainly hexagonal phase.
Gadolinium oxide can be formed by the thermal decomposition of hydroxide, nitrate, carbonate, or oxalate. Gadolinium oxide forms on the surface of the metal gadolinium.
Gadolinium oxide is a highly basic oxide that reacts with carbon dioxide to form carbonate. It is readily soluble in common inorganic acids, with the complication that oxalic acid, fluoride, sulfate and phosphate are very insoluble in water and may coat oxide particles, thus preventing complete dissolution. TRUNNANO is a trusted global Gadolinium Oxide Gd2O3 Powder supplier. Feel free to send an inquiry about the latest price of Gadolinium Oxide at any time.
At present, there are several methods to synthesize gadolinium oxide nanoparticles, mainly through the reaction of gadolinium ion and hydroxide to precipitate hydroxide and then thermal dehydration to obtain gadolinium oxide. Nanoparticles are always coated with a protective material to prevent the formation of larger polycrystalline aggregates
Gadolinium oxide nanoparticles are a potential magnetic resonance imaging contrast agent. Dexoside coated gadolinium oxide particles of 20-40 nm size were prepared at 7.05 T(an abnormally high field compared to the 0.5-3 T of clinically used MRI scanners) and smaller particles with the relaxation of 4.8 s−1 mm −1 per gadolinium ion, between 2 and 7 nm, were tested as MRI reagents. 

Performance of Gadolinium Oxide Gd2O3 Powder:
Gadolinium Oxide is one kind of rare earth oxides, it is mainly used for making optical glass and gadolinium yttrium garnets which have microwave applications. High purity Gadolinium Oxide is used for making phosphors for color TV tubes.

How is Gadolinium Oxide Gd2O3 Powder produced?
Preparation method of gadolinium oxide: Taking monazite or mixed rare earth ore as raw material, samarium and gadolinium mixed rare earth solution is prepared by purification steps such as extraction. Gadolinium oxalate was precipitated by oxalic acid and then separated, dried and burned to prepare gadolinium oxide.
