White Powder ISO14001 Gadolinium Oxide Gd2O3 CAS No 12064-62-9

 White amorphous powder. The relative density is 7.407. Melting point (2330±20)°C. Insoluble in water, soluble in acid.  It is easier to absorb moisture and carbon dioxide in the air. When it reacts with ammonia, gadolinium hydrate is precipitated.

Used as an additive element for yttrium iron garnet and yttrium aluminum garnet. The medical device industry is used as a sensitizing fluorescent material, which can achieve the same effect as the original 200 Ma x-ray machine on a 30 Ma x-ray machine. Used as an additive for optical prisms, as well as for making metal gadolinium, making magnetic bubble materials and controlling materials for nuclear reactors in the atomic energy industry.

Used in various phosphors, neutron absorbing materials in atomic reactors, magnetic bubble materials, and intensifying screen materials. It also has certain uses in optical glass, electronics industry, etc., and is also used as a gadolinium gallium garnet material.

Used as a neutron-absorbing material in atomic reactors, and as phosphors and magnetic material additives, etc.

The rare earth chloride solution obtained from monazite or mixed rare earth ore is extracted by extraction method, and extracted with the P2O4-kerosene-HC1-R system. First, neodymium and samarium are grouped, and the raffinate is used to further extract light rare earths, and extract samarium and heavy rare earths. Enter the organic phase, and then use 2.0 mol/L HCl to strip the medium and heavy rare earths to obtain the samarium-gadolinium enrichment. The mixed rare earths are dissolved, precipitated with oxalic acid, separated, dried and burned to obtain gadolinium oxide. Its Gd2(C2O4)3→Gd2O3+3CO2+3CO
