Web23 jun. 2024 · Silica gel is an oxide compound of silicon with the formula SiO 2. It’s an amorphous and porous form of silicon dioxide that has an irregular tridimensional framework of alternating patterns of silicon and oxygen atoms. The molecular structure of this compound makes it highly absorbent of water. WebWhat is Silica Gel. Formed from silicon dioxide, silica gel is amorphous and produced synthetically into granules that are hard. In appearance, it looks like irregular crystal like beads. Since their micro-porous makeup has cavities that are interlocking, the gel has an extremely high area of surface, it makes for a perfect desiccant of high ...
