    摘要: 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 (Φmax) of the particles in the dispersion is at least about 0.55 as determined from the relationship (I) wherein Φ is the fractional occupied volume of the solids in the fluid, Φmax 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. &eegr;/&eegr;0=[1−(Φ/Φmax)]−[b]Φmax   (1)
