Silica gel, also known as silicic acid gel, is a naturally available substance, plus its superiority in chemical processes that make silica gel a deserving place. Silica gel is essentially silicon dioxide, in the form of hard and soft granules (there are innumerable cavities in the granules). Its simple chemical formula is SiO2.nH2O (n <2), which is made from sodium othosilicates (Na2SiO4) or silicon tetra chloride (SiCl4). Currently, silica gel plays a very important role in the chemical technology from simple to complex. Silica gel is used a lot for catalysis in organic synthesis of petrochemicals, water purification, ...

In everyday life, silica gel is usually found in small packages in a medicine vial, in a food package, in an electronic product. There, the silica gel acts as a desiccant to keep the products from getting wet. Silica gel is hygroscopic due to the capillary phenomenon in millions of its hollow cavities, the water vapor is absorbed and attached to the hollow inside the particles. A quantity of one teaspoon of silica gel has a contact area of ​​a football field. Silica gel can absorb 40% of its water vapor and may cause the relative humidity in the closed container to drop to 40%.

To indicate the water vapor status of silica gel, a little chlorine is added to the cobalt. When it is dry, it will have a slightly greenish color. When it starts to suck, it gradually turns to light blue, then pink, and finally white.

When the silica gel is saturated with water, it can be recycled by keeping it at about 150 ° C for about half an hour or until it returns to green.

Silica gel is highly effective in dehumidifying and hygroscopic compared to other types of desiccant. Where most silica gel production is Shanghai, Qingdao of China.
