Difference Between Silica and Silicon Dioxide

The key difference between silica and silicon dioxide is that the silica is the common name of SiO 2 whereas silicon dioxide is the IUPAC name of SiO 2. Moreover, silicon dioxide refers to the purest form only while silica can be either pure or impure form. Both terms "silica" and "silicon dioxide" refers to the same chemical compound, but they are different in the usage of these terms.
