— Silica is a common naturally occurring mineral, also known as silicon dioxide. Silica can be found in different forms, broadly divided into crystalline and non-crystalline (amorphous). Crystalline silica is the crystalline form of silicon dioxide that forms a major component of most rocks (e.g., granite, slate, sandstone), soil, sand and clay.
