Industry mainly uses the crystalline forms of silica, i.e. quartz and cristobalite. Both are sold as sand, which is a granular material with particles greater than 0.063 millimetres, or as flours that consist of finer particles. Silica is hard, chemically inert and has a high melting point because of the strength of the bonds between the atoms.
