Which is an amorphous form of silicon dioxide, which is synthetically produced in the form of hard irregular granules or beads. A micro porous structure of interlocking cavities gives a very high surface area (800 square meters per gram). It is this structure that makes silica gel a high capacity desiccant. Water molecules adhere to the gels surface because it exhibits a lower vapour pressure than the surrounding air. Silica gel physically adsorbs water vapour into its internal pores.

Standard white silica gel is referred to as being non-indicating. As it adsorbs moisture it remains physically unchanged. Non-indicating silica gel is both cheap and effective, available loose in bulk packs or packed in sachets. Indicating silica gels are colored gels whose colour changes as they absorb moisture.
