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.
For other uses, see Silica (disambiguation) . The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of Template:SiliconTemplate:Oxygen and has been known for its hardness since antiquity.Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.n dimeric silicon dioxide there are two oxygen atoms bridging between the silicon atoms with an Si-O-Si angle of 94Â° and bond length of 164.6 pm and the terminal Si-O bond length is 150.2 pm. The Si-O bond length is 148.3 pm which compares with the length of 161 pm in Î±-quartz.
