Silica gel is a granular, porous form of silica made synthetically from sodium silicate. Despite the name, silica gel is a solid. Silica gel is most commonly encountered in everyday life as beads packed in a semi-permeable plastic. In this form, it is used as a desiccant to control local humidity in order to avoid spoilage of some goods. Because of poisonous dopants and their very high ...

Ever Wonder About Silica Gel? - Science World

29/03/2017  Silica gel packets in the seaweed contain hard little beads. They are made through a process involving sodium silicate and an acid patented by chemistry professor, Walter Patrick, of Johns Hopkins University in 1919. The mixture forms a gel that is then dried out. It is technically a xerogel but gets shortened to gel even though it is hard, just to confuse people. Silica gel is a desiccant ...

Silica gel - Wikipedia

Silica gel is an amorphous and porous form of silicon dioxide (silica), consisting of an irregular tridimensional framework of alternating silicon and oxygen atoms with nanometer-scale voids and pores. The voids may contain water or some other liquids, or may be filled by gas or vacuum. In the last case, the material is properly called silica xerogel. Silica xerogel with an average pore size ...
