Silica gel\u00a0is an\u00a0amorphous\u00a0and\u00a0porous\u00a0form of\u00a0silicon dioxide\u00a0(silica), consisting of an irregular tridimensional framework of alternating\u00a0silicon\u00a0and\u00a0oxygen\u00a0atoms with\u00a0nanometer-scale voids and pores. The voids may contain water or some other liquids, or may be filled by gas or\u00a0vacuum. In the last case, the material is properly called\u00a0silica\u00a0xerogel.
Silica xerogel with an average pore size of 2.4 nanometers has a strong affinity for water molecules and is widely used as a\u00a0desiccant. It is hard and\u00a0translucent, but considerably softer than massive\u00a0silica glass\u00a0or\u00a0quartz; and remains hard when saturated with water.
Silica xerogel is usually commercialized as coarse granules or beads, a few\u00a0millimeters\u00a0in diameter. Some grains may contain small amounts of indicator substance that changes color when they have absorbed some water. Small paper envelopes containing silica xerogel pellets, usually with a “do not eat” warning, are often included in dry food packages to absorb any\u00a0humidity\u00a0that might cause\u00a0spoilage\u00a0of the food.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t <\/div>\n <\/div>\n <\/div>\n

‘Wet’ silica gel, as may be freshly prepared from\u00a0alkali\u00a0silicate\u00a0solutions, may vary in consistency from a soft transparent\u00a0gel, similar to\u00a0gelatin\u00a0or\u00a0agar, to a hard solid, namely a water-logged xerogel. It is sometimes used in laboratory processes, for example to suppress\u00a0convection\u00a0in liquids or prevent\u00a0settling\u00a0of suspended particles.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n

An ice pack or gel pack is\u00a0a portable bag filled with water, refrigerant gel, or liquid, meant to provide cooling. They can be divided into the reusable type, which works as a thermal mass and requires freezing, or the instant type, which cools itself down using chemicals but can only be used once.<\/p>
