Silicon dioxide (silica, Silicon dioxide, silica) is a substance consisting of crystals with high strength, hardness and refractoriness. Silicon dioxide is resistant to acids and does not interact with water. When the reaction temperature rises, the substance interacts with alkalis, dissolves in hydrofluoric acid, and is an excellent dielectric. Natural silicon dioxide, otherwise called silica, is widely used in construction (concrete, sand, sound and thermal insulation materials). Applications of silica: Silica-containing materials have found wide application in both high-tech and daily life. Silicon dioxide is used in the manufacture of glass, ceramics, concrete products, abrasives, as well as in radio engineering, ultrasonic installations, lighters, etc. In combination with a number of ingredients, silicon dioxide is used in the manufacture of fiber-optic cables.
