Quartz glass is different from ordinary glass features

     Infrared can through the quartz glass, quartz glass is made of pure silica special glass, hardness and higher transparency. High temperature resistant quartz glass, wear resistance, anti-oxidation characteristics; while the ordinary glass is mainly a mixture of silica, sodium silicate, calcium silicate composition, none of these advantages. Also should be noted that some of the glass is drag infrared,such as blue and green with nickel oxide and ferrous oxide glass will produce very good on the infrared absorption and hindered. A glass of selectiveabsorption spectrum (with different absorption bands of different) study is a keyindustry in the manufacture of glass, special glass is widely used in military and space industries such as used in outer space is now civilian 73FG series, redresistance rate was 94%, violet resistance rate of 99%, but through the 70%visible light.

     Quartz glass in the silica content are much higher than ordinary glass, quartz glass and silica content in the 99.999% individual.

     Quartz glass has excellent optical performance, not only the visible light transmittance, and through ultraviolet, infrared.

     Quartz glass is a good acid resistant materials, except hydrofluoric acid and 300degrees above the hot phosphoric acid, at low temperature, which is resistant tosulfuric acid, nitric acid, hydrochloric acid, aqua regia, neutral salts, carbon and sulfur corrosion, 30 times the chemical stability of the equivalent of acid resistant ceramic, 150 times the equivalent of Ni Cr alloy and ceramic. Its low temperature resistance, thermal shock resistance, thermal contraction coefficient of specialsmall.

     Quartz glass electric excellent performance at ambient temperature, 10 times of ordinary glass electrical resistance to it, the frequency of the dielectric loss is very small, the withstanding voltage and insulation strength.

     Quartz glass has resistance to space injection line, nature and not throughnuclear fission products.

     Quartz glass for electric light source, semiconductor, optical new skills.

     New light source: low pressure mercury lamp, long arc xenon lamp, halogen lamp,thallium iodide lamp, red inside lamp and germicidal lamp etc..

     Semiconductor: is not the lack of data of semiconductor materials and devicesconsumption process, such as the growth of germanium and silicon single crystalcrucible, boat furnace core tube and bell etc..

     In the new skill category: with its sound, light, electricity and excellentperformance, the radar ultrasonic delay line, infrared tracking direction, prism infrared photography, communication, spectrometer, spectrophotometer,reflecting window lens, large telescope, low-temperature operation window,reactor, jet installation; rocket and the nose cone of the missile, the nozzle and the antenna cover: natural satellite radio radiation; thermal insulating parts,Libra, vacuum adsorption installation, fine casting etc..

     Quartz glass is also used for: chemical industry, metallurgy, electrical engineering, scientific research etc.

     In the chemical area: low temperature acid gas can be extinguished, cooling and ventilation installation, acidic solution evaporation, cooling ceiling materialreceiving, storage and installation, distilled water, hydrochloric acid, nitric acid,sulfuric acid and other preparation and other physical and chemical testingequipment. Acceptance and packaging method of quartz glass tube for low temperature industry: can be used in optical glass and crucible into a phosphorpolite, furnace core tube, gas extinguishing radiator, in optics: nozzle quartz glass and quartz glass wool can be used as a rocket, the spacecraft thermal shield andviewing window, in short, with the modern science and technology development,the quartz glass applied widely in various fields, hand.
