Abstract

Procédé pour la fabrication de poudre frittable de métasilicate de lithium Li2 SiO3. Dans ce procédé, on introduit une proportion stoechiométrique de SiO2 dans une solution aqueuse de LiOH, sèche la suspension obtenue, par atomisation à l'air, à 200-450 degrés C, et calcine la résidu sec pulvérulent entre 500 et 100 degrés C. Application du Li2 SiO3 ainsi obtenu comme matière fertile pour des réacteurs à fusion, pour l'obtention de tritium.Process for the production of sinterable powder of lithium metasilicate Li2 SiO3. In this process, a stoichiometric proportion of SiO2 is introduced into an aqueous LiOH solution, the suspension obtained is dried, by air atomization, at 200-450 degrees C, and the dry powdery residue is calcined between 500 and 100 degrees C. Application of the Li2 SiO3 thus obtained as fertile material for fusion reactors, for obtaining tritium.
