About Gadolinium Oxide Gd2O3 Powder :

Gadolinium oxide is an organic compound. The gadolinium oxide formula is Gd2O3. This form is most commonly found in the rare earth element Gadolinium. It can also be used as a magnetic resonance imaging contrast material.

Gadolinium oxide There are two types of structures. Two structures, the Cubic (CI80 and IA3) (No.206), are very similar to heavy trivalent lanthanide sesquioxides as well. Two types of gadolinium sites are found in cubic structures. They each have a coordination number 6, but they all have different coordination geometries. The monoclinic form (Pearson symbol M30, space group B2/ M, number 12) is the second. Cubic structures are more stable when stored at room temperature. At 1200degC, the phase becomes monoclinic. It is primarily a hexagonal phase above the 2100-22020 melting point.

Gadolinium oxide Can be produced by heating the hydroxide, sodium, carbonate, or oxalate. The surface of the metal gadolinium forms gadolinium dioxide.

Gadolinium oxide, a high-basic oxide, reacts with carbon to create carbonate. It dissolves easily in many inorganic acids. The downside is that fluoride (oxalic acid), fluoride (sulfate), and phosphate are extremely insoluble in liquid water. This may make it difficult to disintegrate completely.

There are many methods available to synthesize currently gadolinium oxide nanoparticles. It is formed mainly by the reaction of gadolinium-ion with the hydroxide to precipitate hydrogen and thermal dehydration to get gadolinium oxide. Protective material is applied to nanoparticles in order to stop the formation of larger polycrystalline aggregates.

Gadolinium oxide nanoparticles These particles could be used as magnetic resonance imaging contrast agents. A deposit-coated gadolinium dioxide particle of size 20-40 nm was prepared at 7.05 T (a high field compared to the 0.5-3 T clinically used MRI scanners). The smaller particles, with a relaxation rate of 4.8 s-1 mm -1 by gadolinium ion between 2-7 nm, were also tested for use as MRI reagents.

Gadolinium oxide Gd2O3 powder performance:

Gadolinium Oxide, one of the rare earth oxides, is used to make optical glasses and gadolinium yttrium garnets with microwave capabilities. Gadolinium oxide of high purity is used to make phosphors that are for use in color TV tubes.

How Gadolinium Oxide Gd2O3 Powder is Produced?

Metal gadolinium method: Dissolve metal gadolinium in nitric acid or hydrochloric acid, add an appropriate amount of sodium nitrate or sodium chlorate, and heat, concentrate, and crystallize the solution to obtain gadolinium nitrate or gadolinium chloride. Then gadolinium nitrate or gadolinium chloride is heated and decomposed to obtain gadolinium oxide. The advantage of this method is that the process is simple and easy to control, but it needs to use a lot of nitric acid or hydrochloric acid, and the production cost is high.

Enrichment method: A mixture of gadolinium oxide and carbon dioxide or water is obtained by melting a gadolinium-containing ore or enrichment with sodium carbonate or sodium hydroxide at high temperatures. The mixture is separated, washed, and dried to obtain gadolinium oxide. This method has the advantages of simple equipment and convenient operation, but the production efficiency is low, and it needs to consume a lot of energy and raw materials.

Ion exchange method: The solution containing gadolinium is passed through the ion exchange column and exchanged with the ion exchanger to obtain gadolinium oxide. The advantages of this method are high purity and convenient operation, but it requires a large number of ion exchangers and eluents, and the production cost is high.

Chemical vapor deposition: The decomposition of gadolinium-containing compounds at high temperatures to produce gadolinium oxide and deposit it on a surface. This method requires the use of high temperature, high pressure or catalyst, and other conditions. The equipment cost is high, but it can be large-scale production.

Biological methods: In recent years, there have been attempts to biosynthesize gadolinium oxide using microorganisms or enzymes. This method uses the action of microorganisms or enzymes to convert gadolinium-containing compounds into gadolinium oxide. The biological method is environmentally friendly and sustainable, but the current production cost is high, and further research and improvement are needed.
