Silica xerogel is tough and hard; it is more solid than common household\u00a0gels<\/a>\u00a0like\u00a0gelatin<\/a>\u00a0or\u00a0agar<\/a>. It is a naturally occurring mineral that is purified and processed into either granular or beaded form. As a\u00a0desiccant<\/a>, it has an average pore size of 2.4 nanometers and has a strong affinity for water molecules.<\/p>\n

Silica gel is most commonly encountered in everyday life as beads in a small (typically\u00a02 x 3 cm)<\/span>\u00a0paper packet. In this form, it is used as a\u00a0desiccant<\/a>\u00a0to control local\u00a0humidity<\/a>\u00a0to avoid\u00a0spoilage<\/a>\u00a0or degradation of some goods. Since such packets may resemble sachets of sugar or salt and because silica gel may have added toxic chemical indicators (see below<\/a>), silica gel packets usually bear warnings for the user not to eat the contents.<\/p>\n","protected":false},"excerpt":{"rendered":"

Silica gel<\/b>\u00a0is a\u00a0granular<\/a>,\u00a0vitreous<\/a>,\u00a0porous<\/a>\u00a0form of\u00a0silicon dioxide<\/a>\u00a0made synthetically from\u00a0sodium silicate<\/a>. Silica gel contains a nano-porous silica micro-structure, suspended inside a liquid. Most applications of silica gel require it to be dried, in which case it is called silica xerogel. For practical purposes, silica gel is often interchangeable with silica xerogel.<\/p>\n
