Top 5 Applications of Silica Gel Beads Silica gel is a form of silicon dioxide (silica), consisting of an irregular tridimensional framework of alternating silicon and oxygen atoms with nanometer-scale voids and pores. The substance is available in amorphous and porous bead form. The chemical is non-toxic, non-flammable, and non-reactive and is stable with ordinary usage. Here are a few applications of silica gel beads:
1. As a Desiccant Moisture can enhance the growth of mold and spoilage in food. It can also damage other items like electronics and can speed up the decomposition of chemicals, such as those in vitamin pills. By storing these materials with silica gel desiccant, these items can be preserved for much longer. The substance is also used to keep the relative humidity (RH) inside a high frequency radio or satellite transmission system.
2. Chemistry Silica gel beads are used in chromatography as a stationary phase. The substance is favored in chemical applications due to its polarity. The chemical is also combined with alkali metals to form a M-SG reducing agent. Silica gel beads are not biodegradable in either water or soil.
3. Gas Absorbent While silica gel beads have a very strong affinity for water, they also act as an exceptional absorbent for various gases. These include gasoline-range hydrocarbons, CO2, C12, sulfur and nitrogen compounds, aromatics, and many others. It is an essential component of gas purification methods.
4. Other Industrial Applications Silica gel is used in water filtration systems to absorb minerals which are dissolved in the water. Silica gel is also used as cat litter, by itself or in combination with more other materials, such as bentonite as it is non-tracking and odorless. It is also used in food industry for various applications.
