Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand.Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product.
Uses of colloidal silica vary. In paper-making plants, colloidal silica is used to drain the liquid from the paper. By allowing the water to leave the paper rapidly, the starch in the paper will remain, increasing the strength of the paper. This solution has many industrial applications as a moisture absorbent in many plants and factories.
