Title (EN) POROUS SILICON-METAL SILICIDE PRODUCTS, AND METHODS FOR PRODUCING THE SAME
(FR) PRODUITS CONTENANT DU SILICIUM POREUX ET DES SILICIURES MÉTALLIQUES, ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) New silicon-metal silicide products and methods of making the same are disclosed. The silicon-metal silicide products may include a silicon-containing comprising a plurality of crystallite silicides. The product may have a specific surface area of at least 1 m2/gram, and the plurality of crystallite silicides may have an average crystallite size of from 5 nanometers to 500 nanometers. The product may have pores with an average pore size of from about 2 nm to 1 um. The silicon-metal silicide products may be made by contacting a porous precursor product with a magnesium-containing material. The porous precursor product includes a silicon material having some Si-O bonds and metal in contact with the porous precursor product. During the contacting, the magnesium-containing material may reduce the silicon, and metal silicides may form from the metal.
(FR) L'invention concerne de nouveaux produits contenant du silicium et des siliciures métalliques, et leurs procédés de fabrication. Les produits contenant du silicium et des siliciures métalliques peuvent inclure un composant contenant du silicium renfermant plusieurs cristallites de siliciures. Le produit peut avoir une surface spécifique d'au moins 1 m2/gramme, et les cristallites de siliciures peuvent avoir une dimension moyenne comprise entre 5 nanomètres et 500 nanomètres. La dimension moyenne des pores du produit peut être comprise entre environ 2 nm et 1 um. Les produits contenant du silicium et des siliciures métalliques peuvent être fabriqués en mettant en contact un produit précurseur poreux et un matériau contenant du magnésium. Le produit précurseur poreux comprend un matériau en silicium comportant des liaisons Si-O et un métal en contact avec le produit précurseur poreux. Pendant le contact, le matériau contenant du magnésium peut réduire le silicium, et des siliciures métalliques peuvent se former à partir du métal.
