The present invention relates to a dispersion of porous surface modified silica particles including fluid and the porous particles, wherein the maximum fractional occupied volume (.PHI.max) of the particles in the dispersion is at least about 0.55 as determined from the relationship (I) wherein .PHI. is the fractional occupied volume of the solids in the fluid, .PHI.max is the asymptotic limit (maximum) of fractional occupied volume as the viscosity approaches infinity, b is the intrinsic viscosity, no is the viscosity of the fluid and n is the viscosity of the dispersion.
La présente invention concerne une dispersion de particules de silice à surface modifiée, poreuses, comprenant un liquide et les particules poreuses, le volume fractionnel occupé maximum (.PHI.max) des particules dans la dispersion représentant au moins environ 0,55 tel que déterminé à partir de la relation (I), dans laquelle .PHI. représente le volume fractionnel occupé des solides dans le liquide, .PHI.max représente la limite asymptotique (maximum) de volume fractionnel occupé lorsque la viscosité approche l'infini, b représente la viscosité intrinsèque, .eta.o représente la viscosité du liquide et .eta. représente la viscosité de la dispersion.
