Abstract

L'invention concerne une silice polymorphe de synthèse. Elle se rapporte à une silice polymorphe qui, après calcination pendant 1 h à 600 degrés C, a un indice moyen de réfraction de 1,39 et un poids spécifique de 1,70 à 25 degrés C. La capacité d'absorption de vapeur d'eau est très faible et le spectre d'absorption infrarouge indique une absence pratiquement totale d'absorption entre 3700 et 3100 cm**-1. Application à la synthèse de silice très hydrophobe pour l'absorption des matières organiques
