Silicon dioxide is an inorganic compound with the chemical formula SiO2. Silicon atoms and oxygen atoms are arranged in long-range order to form crystalline silica, and short-range order or long-range disorder are arranged to form amorphous silica. In the silicon dioxide crystal, the silicon atom is located in the center of the regular tetrahedron, and the four oxygen atoms are located at the four vertex corners of the regular tetrahedron. Many such tetrahedrons are connected through the oxygen atoms at the vertex corners. Each oxygen atom is Two tetrahedra are common, that is, each oxygen atom is bonded to two silicon atoms. Pure natural silica crystal is a hard, brittle, insoluble, colorless and transparent solid, often used in the manufacture of optical instruments, etc.
