quartz glass container

good quality quartz glass material , high accurate , many sizes ; many items

Quartz boat and name quartz glass, quartz glass is contain silica material, such as crystal, silica. Four silicon oxide as raw materials high temperature melting into the system. The silica content than ordinary glass much higher, general quartz glass silica content in 99.999%. Quartz glass has excellent optical performance, not only visible light transmittance is very good, and through ultraviolet ray, infrared. Quartz glass is good acid materials, except hydrofluoric acid and 300 degrees of above thermal phosphoric acid outside, at high temperatures, it ability sulfuric acid, nitric acid, hydrochloric acid, wang, neutral salt class, carbon and sulfur and erosion, the chemical stability is equivalent to acid ceramic 30 times, equivalent to nickel chrome alloy and ceramic 150 times, it is high temperature resistant, heat resistant shock, coefficient of thermal expansion special small.

Quartz glass also has resistance to cosmic radiation, and opaque nuclear fission product properties. Quartz glass is mainly used for electric light source, semiconductor, optical new technology, etc. New light source aspects: do high pressure mercury lamp, long arc xenon lamp, halogen lamp, thallium iodide light, infrared light and germicidal lamp, etc. Semiconductor aspects: is semiconductor materials and devices production process the essential material, such as growth germanium and silicon single crystal's crucible, the boat furnace core and cover, etc. In the new technology areas: with its sound, light, electricity excellent performance, do radar on the ultrasonic delay line, infrared tracking direction finding, infrared camera, newsletter, spectrograph, spectrophotometer of prism, lens, large astronomical telescope reflection window, high temperature operation window, reactor, radioactive device; The rockets, missile nose cone, nozzle and radome: satellite radio insulation parts, radiation; Thermobalance, vacuum adsorption device, precision casting and so on. Quartz boat is also used in: chemical, metallurgy, electrical, scientific research, etc In the chemical aspects: to do high temperature acid gas combustion, cooling and ventilation device, acidic solution evaporates, cooling suction content close, storage device, distilled water, hydrochloric acid, nitric acid, sulfuric acid, preparation and other physical chemistry experiment supplies. At high temperature for an inheritance: to do optical glass, crucible into fluorescent body polite, electric furnace core tube, gas combustion radiator, in optical aspects: quartz glass and quartz glass cotton can make the rocket nozzle, the spacecraft heat shield and observation window, etc., in a word, along with the development of modern science and technology, quartz glass in each field get more extensive application
