aldawaa: How to prepare silica gel slurry for TLC?

In most silica gels it is put in at a level of from 10-15% to give good binding to the glass plates For coating five 20x20 plates about 30g TLC silica gel to 60ml water is needed Once made then the time available to put in the applicator and to pull across the glass plates is limited since the binder will hydrate and the slurry will no longer be a flowing liquid The other formulation

Numerical Investigation of Silica Gel

The silica gel (SiO 2 NH 2O) is amorphous synthetic silica whose pore structure creates by agglomeration substantially spherical microparticules of approximately uniform size and between 2 and 20 nm This structure is responsable for the very large surface area typically 500-800m/g it is hydrophobic and has the advantage of adsorbing moisture The silica gel has a high

Silicon Silica Silicates and Silicone

Silicon links up with oxygen (which makes up 55% of the earth's crust) to form the most common suite of minerals called the silicates Quartz feldspars olivine micas thomsonite jadeite and prehnite are all silicates There is so much oxygen around that pure native silicon is almost never found naturally Silica is a bit trickier concept It refers the combination of silicon plus oxygen
