Silica gel is made from sodium silicate, having very strong adsorbing quality because silica gel is more solid than other adsorbers.

However, silica gel is having a high surface area around 800m2/g allows water adsorbs readily when the temperature near or high than 40 degree Celsius. Silica gel is either the beaded or crystalizes form of sodium silicate which is solid than other adsorbents and can adsorb water molecules. Silica gel is also used to dry the air in industrial compressed, heated and heatless air systems, also use for catalyst carrier. It absorbs moisture from the air and gases, preventing damage of industrial air due to moisture or condensation.
