Silicon dioxide is an inorganic compound with the chemical formula SiO2. Silicon atoms and oxygen atoms are arranged in a long-range order to form crystalline silicon dioxide, and short-range order or long-range disordered arrangement to form amorphous silicon dioxide.
In a silicon dioxide crystal, the silicon atom is located in the center of the regular tetrahedron, and the four oxygen atoms are located on the four top angles of the regular tetrahedron, and many such tetrahedrons are connected by the oxygen atoms of the top angles, each oxygen atom is shared by the two tetrahedrons, that is, each oxygen atom is combined with two silicon atoms.
The simplest form of silicon dioxide is SiO2, but it does not represent a simple molecule (only the ratio of the number of atoms of silicon and oxygen in the silicon dioxide crystal).
Pure natural silica crystal, is a hard, brittle, insoluble colorless transparent solid, often used in the manufacture of optical instruments.Silicon dioxide is the manufacturing of glass, quartz glass, water glass, optical fiber, electronic industry important components, optical instruments, crafts and refractory materials, is an important material for scientific research.
When silica crystallization is crystal, after gelatinization and dehydration is agate, the aqueous colloid solidified to become opal, silica grains less than a few microns, it is composed of chalchalith, chert, secondary quartzite.
Purpose
1.silica: mainly used as a lubricant, anti-sticking agent and flow aid.
2. Silica for food and beverages: Flow aid, anti-caking performance.
3. Silica for rubber: Eliminates internal tension, delamination and cracking.
4. Silica for paints and coatings: Controls rheology, prevents bright spots, resists sagging, resists ultraviolet rays, prevents sedimentation, and enhances corrosion resistance.
5. Silica for papermaking: Fast ink absorption speed, high whiteness, clear and vivid printed images.
6. Silica for molds: It features excellent dispersibility, compatibility, high transparency and high whiteness.
7. Other silica is also produced for use as a decolorizing agent in petroleum and edible oil, a grinding agent in toothpaste, and a special matting agent for leather, etc.
