Abstract

Pelletized silica particles characterized by a round shape and a monomodal particle size distribution are produced by dispersing silica particles into water, adding water to the dispersion, mixing with alkoxisilane, pouring the mixture into an organic solvent, filtering and washing the silica particles obtained. The pelletized silica particles can be used to produce glass monoliths.

Claims (21)
