Abstract

Abstract Translated from French L'invention décrit la synthèse d'une matière minérale apparentée à un constituant rare du sol, l'imogolite. On en effectue la synthèse en provoquant, à un pH de 3,5 à 5,0, la digestion de complexes solubles d'hydroxy-aluminium fraîchement formés à pH 3,5 à 5,5 en solution aqueuse avec une concentration restreinte en Al. A une concentration inférieure à 1 % de matière sèche, ce produit forme des gels. Il peut servir de tamis moléculaire, de catalyseur, d'épaississant, etc. The invention describes the synthesis of a mineral material related to a rare constituent of soil, imogolite. It is synthesized by causing, at a pH of 3.5 to 5.0, the digestion of soluble, freshly formed hydroxy-aluminum complexes at pH 3.5 to 5.5 in aqueous solution with a restricted concentration of Al. At a concentration of less than 1% dry matter, this product forms gels. It can be used as molecular sieve, catalyst, thickener, etc.
