Abstract

La présente invention concerne un matériau de type poudre de dioxyde de silicium et son procédé de préparation. Ledit matériau de type poudre de dioxyde de silicium est un matériau présentant une taille de particule pouvant varier de 0,1 à 30 microns, qui est produit par agrégation accélérée d'une substance organique hydrolysable, en utilisant un sol de silice comme matière première. Ledit procédé de préparation comprend les étapes consistant à mélanger la substance organique hydrolysable avec le sol de silice selon un certain rapport à température ambiante, à faire réagir le tout pendant 1 à 48 heures sous agitation et à faire passer le produit résultant à travers un filtre-presse, avant de le déshydrater une fois la réaction arrivée à son terme. Ledit matériau de type poudre de dioxyde de silicium trouve de nombreuses applications, son procédé de production est simple et son coût de production peu élevé. Il est possible de préparer des matériaux de type poudre de dioxyde de silicium présentant des tailles de particule différentes en ajustant la teneur en substance organique hydrolysable.
