Description
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 lresulting in the formation of 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 extraction[1]
Application
Silica gel was used to compare MCM-41 type mesoporous adsorbents.[3]
