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.
Silicon dioxide is the main raw material for making glass. Glass made of silica alone is called quartz glass, which has characteristics such as high temperature resistance and ultraviolet light transmission. Silica is also an important raw material for the manufacture of optical fiber. A large amount of silica is used as a reinforcing agent for rubber, an opening agent to prevent the adhesion of plastic films, an anti-settling agent for pigments, a matting agent for coatings, a viscosity regulator, a pharmaceutical excipient, a catalyst carrier and for cosmetics.
About 70% of white carbon black is used as a reinforcing filler for natural rubber and synthetic rubber, and other fillers for synthetic resins, ink thickening agents, anti-settling agents for pigments in coatings, matting agents, soft polishes for vehicles and metals, and anti-settling agents in emulsifiers. It can also be used as a pesticide carrier and filler for light weight newsprint. Due to the advantages of good electrical insulation, low heat generation, light color of products and no pollution, white carbon black is also widely used in rubber hose, tape, heat-resistant gasket, rubber roller and medical products.
