Silica Gel is a well-known desiccant used mainly to adsorb water vapour from the surroundings. Synthetically manufactured from sodium silicate, Silica Gel is mainly a granular and porous type of Silicon Dioxide (SiO2). The adsorbent is manufactured both in granular (with hard, irregular shape of crystals) and beaded (even-sized spherical) form. Silica Gel is known to have a very large surface area, which exposes it to maximum water vapour and hence it is able to absorb more moisture.
