What exactly is Gadolinium oxide?
Gd2O3 is the chemical formula for gadolinium dioxide. It has a molecularweight of 362.498000 with a melting temperature of 2330 and a density 7.407. It is white in color.
Physical And Chemical Properties of Gadolinium Oxide
Gadolinium oxide is a white, odorless and amorphous powder. It is not soluble, however it can be broken down by acid to create the equivalent salt. Exposure to air makes it easy to absorb carbon dioxide from the air and cause it to deteriorate. It reacts with ammonia and can precipitate gadolinium-hydrate.
Preparement Method of Gadolinium Oxide
To make micron-grade gadolinium dioxide powder, mix 10g with hydrochloric acids at 3.23mol*L. Then heat the mixture until it is completely reacted. Finally, add some polyethylene glycol to the solution (which disperses the gadolinium salt). After the colloidal precursor has been stable for quite some time, stir the mix to disperse and dissolve polyethylene glycol. Deionized water was mixed with the prepared colloid. This gave rise to 500 mL suspension. It was then dried by spray drying. For nano-gadolinium, oxide is obtained by calcining the precursor at different temperatures (600-900) over several hours.
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 polyether ether 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, chemical, machine, and machinery.
