Four high-temperature oxidation of silicon as the raw material made of melting. The silica content is much higher than ordinary glass, quartz glass, silica content generally 99.999%. Quartz glass has excellent optical properties, not only visible light transmission are particularly good, and through the ultraviolet, infrared. Quartz glass is a good acid-proof materials, in addition to hydrofluoric acid and hot phosphoric acid above 300 degrees outside, at a high temperature, it capability sulfuric acid, nitric acid, hydrochloric acid, aqua regia, neutral salts, carbon and sulfur corrosion, the chemical stability of acid-resistant ceramic equivalent of 30 times, equivalent to nickel-chromium alloy and ceramic 150 times, it is high temperature, thermal shock, thermal expansion coefficient very small. Excellent electrical properties of quartz glass, at room temperature, its resistance is equivalent to 10 times that of ordinary glass, on the whole frequency dielectric loss is very small, large compressive strength insulation. Quartz glass is also resistant to cosmic radiation, and non-transparent nature of nuclear fission products. Quartz glass is mainly used for electric light source, semiconductor, optical technology and so on. New light source areas: Do high-pressure mercury lamp, a long arc xenon lamp, tungsten, thallium iodide lamp, infrared lamps and germicidal lights. Semiconductor areas: Semiconductor materials and devices essential for the production process materials, such as the growth of germanium, silicon crystal in the crucible, boat pan heater core pipe and the bell and so on. In the field of new technologies: With its sound, light, the excellent electrical properties, making ultrasonic delay line radar, infrared tracking direction finding, infrared photography, communication, spectrograph, spectrophotometer prism, lens and large windows reflecting telescopes, high temperature window, reactors, radioactive device; Rocket, missile nose cones, nozzles and radome: Satellite radio insulation parts, radiation; Heat scales, vacuum devices, precision casting.
