General description

Silica gel is a rigid 3D network of colloidal silica.1 It is exclusively used as a support material for the active titanium (III) centers in Ziegler-Natta catalysts. Silica gel allows a controlled fragmentation leading to form uniform polymer particles with narrow particle size distribution and high bulk density.2 Silica gel is classified as below:
a. Aquagel - pores are filled with water
b. Xerogel - by the process of evaporation, aqueous phase in the pores are removed
c. Aerogel - Solvent removed by supercritical extraction1
Silica gel is dehydrated jelly of silicic acid having specific surface of 700-800 m2/g and is suitable as drying agent for gases.3
