Thermochemical and electrochemical study of sodium and zinc insertion into α-UO 3 − y and α-U 3O 8

New sodium and zinc insertion compounds of the uranium oxides UO 2.95(α-UO 3) and UO 2.67(α-U 3O 8), were synthesized at ambient temperature. Enthalpies of formation were measured calorimetrically and corresponding free energies of formation were determined electrochemically. Electronic changes on i...

Summary:New sodium and zinc insertion compounds of the uranium oxides UO 2.95(α-UO 3) and UO 2.67(α-U 3O 8), were synthesized at ambient temperature. Enthalpies of formation were measured calorimetrically and corresponding free energies of formation were determined electrochemically. Electronic changes on insertion were monitored by measurements of magnetic susceptibilities.
