Technology Process of Gadolinium

There total 2 articles about Gadolinium which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

gadolinium + hydrogen (1333-74-0) → GdH3 (13572-97-9)

Guidance literature:

codeposition of Gd and in situ generated hydrogen atoms (from thermallydissociated H2 in tungsten cell at ca. 2600 K); trapping of molecules in solid Ar or Ne matrix;

DOI:10.1063/1.441969

Reference yield:

GdMn2 → gadolinium dihydride + manganese + GdH3 (13572-97-9)

Guidance literature:

With H₂; In neat (no solvent); hydrogenation at 513 K under 50 atm H2; not isolated; detn. by X-ray diffraction;

DOI:10.1016/0022-5088(90)90132-4

upstream raw materials:
