Silica or silicon dioxide (SiO 2) is a chemical compound consisting of one silicon and two oxygen atoms.Quartz is a common mineral with the same chemical composition but quartz and silica are not synonyms. Specific minerals always have a definite crystal structure while chemical compounds have no such restriction — just like every piece of carbon is not a diamond.
