Cette technique de transformation de particules siliceuses en entités granulaires ou monolithiques consiste, d'une part, à agréger les particules pour obtenir une masse de consistance plastique par l'interaction des particules siliceuses et d'une solution aqueuse contenant un hydroxyde de métal alcalin et, d'autre part, à faire s'évaporer l'eau du mélange. Ces opérations sont suivies d'un traitement destiné à cuire le mélange à une température à même de provoquer la formation de liaisons permanentes entre les particules siliceuses.
A method for converting siliceous base particles into granular or monolithic forms, comprising a step for aggregating the particles which provides a mass having a plastic consistency through the interaction of the siliceous base particles with an aqueous solution which comprises an alkaline metal hydroxide and a step for evaporating the water of the mixture, followed by a treatment for baking the mixture at a temperature which is capable of producing permanent bonds among the siliceous base particles.
