18 Uses of Silica Gel Packets Worth Knowing
Silica gel, is produced synthetically from its compound, ‘sodium silicate’. With a glassy appearance and grainy texture, this naturally occurring compound is processed to be used as a siccative.
|Dry Action at War!
Silica gel was used in World War I for soaking up vapors and gases in canisters.
Silica gel is amorphous and highly poriferous in nature. Its texture is similar to commonly-used compounds such as agar-agar or gelatin. In addition, it is stronger than both these varieties. It is a very powerful moisture-absorbent as it has high affinity to water particles. Therefore, it is mainly used as a drying agent. Silica gel is processed and packed in small-sized paper sachets. These sachets are usually holey for water vapor to be absorbed by the gel.
Advantages of Silica Gel
