Préparation par mécanosynthèse d’apatites strontiques dopées au lanthane et au césium

Abstract: britholites ont suscite ´un grand inte ´re ˆt aupre `s des chercheurs en raison de leurs applications potentielles en tant que matrices pour le confinement de certains de ´chets se ´pare ´s issus de l'industrie nucle ´aire, comme les actinides mineurs et certains produits de fission. Cependant, leur pre ´paration ne ´cessite des tempe ´ratures e ´leve ´es, de l'ordre de 1400 8C. Dans le pre ´sent travail, nous rapportons la pre ´paration par me ´canosynthe `se d'apatites strontiques dope ´es au lanthane et au … Show more

“…In order to get a better understanding of the evolution of their properties with the substitution degree, a systematic study of lanthanide-substituted fluoro-and oxyapatites has been undertaken in our laboratory [36][37][38][39][40][41]. In this paper, we investigate the ionic conductivity of the Ca 6 La 4 (PO 4 ) 2 (SiO 4 ) 4 F 2 and Ca 4 La 6 (SiO 4 ) 6 F 2 samples using impedance spectroscopy.…”

“…On the contrary, the mechanochemical synthesis involves only a solid-state reaction at room temperature [22,23]. Therefore, this method appears quite attractive for the preparation of this kind of materials [24,25]. Besides its low energy consumption, simplicity and speed, it is suitable for industrial production.…”
