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.
Fumed silica, also known as pyrogenic silica, is a non-crystalline, fine-grain, low density and high surface area silica. Not to be confused with silica fume, also known as microsilica. The production of precipitated silica starts with the reaction of an alkaline silicate solution with a mineral acid.
