Silica gel is tough and hard; it is more solid than common household gels like gelatin or agar.It is a naturally occurring mineral that is purified and processed into either granular or beaded form.As a desiccant, it has an average pore size of 2.4 nanometers and has a strong affinity for water molecules.Silica gel is most commonly encountered in everyday life as beads in a small (typically 2 x 3 cm) paper packet.s a desiccant, it has an average pore size of 2.4 nanometers and has a strong affinity for water molecules.

Q: What is Silica Gel? Silica gel is form of silicon dioxide, Si02, the material that occurs in nature as sand. The difference between silica gel and sand is that sand is a crystalline, non-porous form, whereas silica gel is non-crystalline and highly porous. Silica gel is synthetically manufactured from the chemical reaction between sodium silicate and sulfuric acid.
