Silica Defined. Silica is another name for the chemical compound silicon dioxide. Each unit of silica includes one atom of silicon and two atoms of oxygen. If you have never heard of silica before, you might be surprised to hear that you probably come into contact with it every day.
Scientific Facts: Silica Silylate is a silica compound in which some of the hydroxyl groups on the surface have been replaced by trimethylsiloxy groups. Instead of trimethylsiloxy groups, Silica Dimethyl Silylate has dimethyl silyl groups which replace some of the surface hydroxyl groups.
