What is silica? Silica is one of the most common naturally occurring elements on the planet. Silica, the mineral compound silicon dioxide (SiO2), is found in two forms crystalline or noncrystalline (also referred to as It only takes a very small amount of the very fine respirable silica dust to create a health hazard.
Silicon dioxide is obtained by mining and purification of the resulting mineral. Quartz comprises more than 10% by mass of the earth's crust. Commercial silicon dioxide is also produced, almost always via the processing of quartz, synthetically on a very large scale. Since it is so abundant, quartz is present in nearly all
