SILICA, SILICA GEL silica, silica gel A material composed of silicon dioxide, SiOZ. Silica is a typically support material used in HPLC and GC columns. It is stable except at high pH or in hydrofluoric acid (HF) solutions. For HPLC silica is prepared from the controlled polymerization of silicic acid, Si(OH)4. Final HPLC- grade silica is porous, pellicular or nonporous, spherical or irregular in shape, derivatized or underivatized, activated or base deactivated. Sil iCiC acid A commonly ...

by A. Whelan

Silica gel, precipitated and fumed silica are amorphous forms of silica which may be considered as being condensed polymers of silicic acid. Naturally occurring forms of silica (such as diatomaceous earth, rottenstone and tripoli) are micro- crystalline, or cryptocrystalline, forms. Crystalline forms of silica are obtained by, for example, crushing, pulverizing and purifying quartzite. The chemical inertness , and purity (> 99.6% silica) of this crushed compound, make it a useful reinforcing ...
