Precipitated Silica: An Important Industrial Mineral Precipitated silica, also known as silica gel, is a fine, white, porous, non-crystalline form of silica produced by artificial means. It is synthetically manufactured by neutralizing a soluble silicate with an acid resulting in the formation of a gel-like precipitate. The precipitate is washed to remove salt and then dehydrated to produce a high-purity amorphous form of silica.
