Silicon dioxide is an oxide of silicon, most commonly found in nature as quartz and in various living organisms. Silica is the major constituent of sand and is poorly soluble. Is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product.

Inhaling finely divided crystalline silica is toxic and can lead to severe inflammation of the lung tissue, silicosis, bronchitis, lung cancer, and systemic autoimmune diseases, such as lupus and rheumatoid arthritis. Inhalation of amorphous silicon dioxide, in high doses, leads to non-permanent short-term inflammation, where all effects heal.
