Quartz glass is a good acid-resistant material. Except hydrofluoric acid and hot phosphoric acid above 300 degrees, it can resist the corrosion of sulphuric acid, nitric acid, hydrochloric acid, Aqua regia, neutral salts, carbon and sulphur at high temperature. Its chemical stability is 30 times that of acid-resistant ceramics, 150 times that of nickel-chromium alloys and ceramics. It has high temperature resistance, thermal shock resistance and low thermal expansion coefficient.

Quartz glass has excellent electrical properties. At room temperature, its resistance is 10 times that of ordinary glass. Its dielectric loss to all frequencies is very small, and its insulation voltage resistance is high.

Quartz glass also has properties of cosmic radiation resistance and impermeability to nuclear fission products.

Quartz glass is mainly used in electric light source, semiconductor, new optical technology and so on.

New light sources: high pressure mercury lamp, long arc xenon lamp, tungsten iodide lamp, thallium iodide lamp, infrared lamp and bactericidal lamp.

Semiconductor: Semiconductor materials and devices in the production process of indispensable materials, such as germanium growth, silicon single crystal crucible, vessel furnace core tube and bell cover.

In the field of new technology: using its excellent performance of acoustics, optics and electricity, making ultrasonic delay line on radar, infrared tracking direction finding, prism of infrared photography, communication, spectrograph, spectrophotometer, lens, reflection window of large astronomical telescope, high temperature operation window, reactor, radioactive device; rocket, nose cone of missile, nozzle and antenna cover: wireless of artificial satellite Electrical insulating parts, radiation, thermal balance, vacuum adsorption device, precision casting, etc.

In chemical industry, it can be used as combustion, cooling and ventilation devices for high temperature acid-resistant gases, evaporation of acid solutions, absorption of cooling materials, storage devices, distilled water, preparation of hydrochloric acid, nitric acid, sulfuric acid and other physical and chemical experimental materials. In the high temperature industry: can be used as optical glass, crucible into fluorescent object passenger, furnace core tube, gas burning radiator, in the optical aspect: quartz glass and quartz glass wool can be used as rocket nozzle, spacecraft heat shield and observation window, etc., in short, with the development of modern science and technology, quartz glass has been more widely used in various fields.
