Structural study of a rare earth-rich aluminoborosilicate glass containing various alkali and alkaline-earth modifier cations
Arnaud Quintas, Daniel Caurant, Odile Majérus +4
A rare-earth rich aluminoborosilicate glass of composition (given in wt.%): 50.68 SiO2 - 4.25 Al2O3 - 8.50 B2O3 - 12.19 M2O - 4.84 M'O - 3.19 ZrO2 - 16.35 Nd2O3 (where M and M' are…
Structural characterization of Nd-doped calcium aluminosilicate glasses designed for the preparation of zirconolite (CaZrTi2O7) -based glass-ceramic
Pascal Loiseau, Daniel Caurant, Noël Baffier +4
This work concerns glasses belonging to SiO2-Al2O3-CaO-ZrO2-TiO2-Nd2O3 system that lead to zirconolite crystallization in their bulk after nucleation + crystal growth thermal treat…
Structural characterization of SiO2-Na2O-CaO-B2O3-MoO3 glasses
Daniel Caurant, Odile Majérus, Edouard Fadel +4
Nuclear spent fuel reprocessing generates high level radioactive waste with high Mo concentration that are currently immobilized in borosilicate glass matrices containing both alka…
Effect of changing the rare earth cation type on the structure and crystallization behavior of an aluminoborosilicate glass
Arnaud Quintas, Daniel Caurant, Odile Majérus +2
An aluminoborosilicate glass, containing high amount of rare earth (RE) accordingly to the following composition 50.68 SiO2 - 4.25 Al2O3 - 8.50 B2O3 - 12.19 Na2O - 4.84 CaO - 3.19…
Hot Carrier Solar Cells : In the Making ?
A. Le Bris, L. Lombez, Jean Francois Guillemoles +9
Hot carrier solar cells allow potential efficiency close to the thermodynamical limit in ideal conditions. However, the feasability of such devices has not been clearly stated so f…
Characterization of the Microstructure of Zirconolite-Based Glass-Ceramics
P. Loiseau, I. Touet, Daniel Caurant +2
December 1991 legislation in France has spurred research on enhanced separation and conditioning or transmutation of long-lived radionuclides from high level radioactive wastes (HL…
