Superiority
Precipitated silica is a relatively pure form of the mineral silica, which is produced by the chemical process known as precipitation. In chemical precipitation, a solid forms from a liquid due to a chemical reaction. Precipitated silica is formed by mixing solutions of sodium silicate with sulfuric acid in water. A chemical reaction occurs, and pellets of pure silica form.
