Silica gel, high-purity grade, with approx. 15% calcium sulfate and fluorescent indicator, GF254, for thin layer chromatography
Silica gel is a rigid 3D network of colloidal silica. 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. Silica gel is classified as below:a. Aquagel – pores are filled with waterb. Xerogel – by the process of evaporation, aqueous phase in the pores are removedc. Aerogel – solvent is removed by supercritical extraction
