Applications

Silica gel was used to compare MCM-41 type mesoporous adsorbents. It is exclusively used as a support material for the active titanium(III) centers in Ziegler-Natta catalysts. Silica gel allows a controlled fragmentation resulting in the formation of uniform polymer particles with narrow particle size distribution and high bulk density. It is a useful product for column chromatography.

Notes

Store at room temperature. Incompatible with oxidizing agents.
