kieselsäuregel

Kieselsäuregel, also known as silica gel, is an amorphous and porous form of silicon dioxide. It is typically produced in the form of small, translucent beads or granules. Its high surface area and porous structure are key to its properties. Kieselsäuregel is manufactured through a chemical process involving the reaction of sodium silicate with an acid. This process results in a gel-like substance that is then dried and processed into its final granular form.

The primary use of kieselsäuregel is as a desiccant, meaning it is employed to absorb moisture from the surrounding environment. Its ability to adsorb water vapor makes it highly effective in protecting sensitive goods from humidity damage during storage and transportation. Common applications include packaging for electronics, pharmaceuticals, and food products, where it helps maintain product integrity and extend shelf life. It is also used in laboratories for chromatography, a technique for separating mixtures. In some consumer products, like shoe boxes or certain types of packaging, small packets of kieselsäuregel are included to absorb ambient moisture. It is important to note that kieselsäuregel is generally considered non-toxic but should not be ingested.
