Abstract

Linvention a trait à un procédé de fabrication de compositions de siliciure de métaux alcalins ainsi quà des compositions obtenues par ce procédé. Ce dernier consiste à mélanger un métal alcalin à du silicium et à chauffer ce mélange à une température inférieure à 475 °C environ. Les compositions obtenues ne réagissent pas avec de loxygène sec. Linvention porte également sur des compositions de siliciure de sodium présentant un motif de diffraction de rayons X sur poudre comprenant au moins trois pics présentant des angles 2 téta sélectionnés parmi : 18,2; 28,5; 29,5; 33,7; 41,2; 47,4 et 56,2; et un pic spectral 23Na MAS NMR en état solide à 18 ppm environ. En outre, linvention concerne des procédés pour supprimer une substance volatile inflammable, de manière contrôlée. Linvention concerne encore des compositions de siliciure de métaux alcalins réagissant avec leau pour produire du gaz hydrogène.
