Abstract

Dispersion aqueuse colloïdale de fumée de silice, d'acide et de stabilisant comprenant au moins environ 40 % en poids de fumée de silice, de l'acide en une quantité d'environ 0,025 % à environ 0,50 % de la quantité pondérale de fumée de silice et suffisamment de stabilisant pour élever le pH de dispersion jusqu'entre environ 7 et 12, en dispersion dans de l'eau. La concentration en fumée de silice colloïdale peut s'élever jusqu'à environ 65 % en poids. La surface spécifique de la fumée de silice est utilement de l'ordre de 50 m2 par g.Colloidal aqueous dispersion of silica fume, acid and stabilizer comprising at least about 40% by weight of silica fume, acid in an amount from about 0.025% to about 0.50% of the weight amount of silica fume and enough stabilizer to raise the dispersion pH to between about 7 and 12, dispersed in water. The concentration of colloidal silica smoke can be up to about 65% by weight. The specific surface of the silica smoke is usefully of the order of 50 m2 per g.
