Gadolinium Oxide: Chemical and Physical Properties
Gadolinium oxide is a white, odorless and amorphous powder. It is not soluble, however it can be broken down by acid to produce the appropriate salt. Exposure to air makes it easy to absorb carbon dioxide from the air and cause its deterioration. It reacts with ammonia and can precipitate gadolinium-hydrate.
Gadolinium oxide preparation method
Make 10g micron-grade gadolinium dioxide powder by mixing it with hydrochloric acids at 3.23mol*L. Once the reaction has completed, add some polyethylene glycol to the mixture (which disperses the gadolinium salt). Once the colloidal precursor is stable, you can stir to dissolve and disperse any polyethylene glycol. Then add deionized tap water to bring down the Gd concentration to 0.22mol*L. After cooling to room temperature, stir in dropwise ammonia water, a solution of gadolinium chloride, until pH reaches 9. Continue to stir for 30 minutes, before generating gadolinium hydroxide collloid. Deionized water was mixed to the colloid and stirred vigorously. 500mL suspension solution was created. The powder was then dried after it was uniformly distributed to create a precursor. For nano-gadolinium, oxide is obtained by calcining the precursor at different temperatures (600-900) over several hours.
Gadolinium Oxide: Application prospects
1. It is used in the preparation of gadolinium oxide ceramics. The solubility of gadolinium in stainless steel and nickel-based metals is not known. A second-phase, gadolinium-rich eutectic product (Ni Cr, Gd) can easily be formed along the grain boundary. The possibility of anisotropy and second phases from hot rolling makes it possible to create them. Gadolinium oxide can be added to composite materials for a better neutron shielding. The advantages of gadolinium dioxide ceramics include high mechanical strength, excellent wear resistance and corrosion resistance.
2. It is used for the preparation of polyetheretherketone compound with gadoliniumoxid. It is one of the most important special engineering plastics families that has ever been created. The resin has excellent heat resistance, radiation resistance and hydrolysis resistance. It also offers high wear resistance and fatigue resistance. The product has been used extensively in many areas, including aerospace, medical, health, electronic devices, chemicals and machinery.
