Description
Quartz boat - Introduction:
Quartz glass is a silica-containing material, such as crystal, silica. Four high-temperature oxidation of silicon as the raw material from melting. The silica content is much higher than ordinary glass, quartz glass, silica content in general 99.999%. Quartz glass has excellent optical properties, particularly good not only visible light transmission, and through the ultraviolet and infrared.
Quartz glass is a good acid-proof materials, with the exception of hydrofluoric acid and hot phosphoric acid above 300 degrees outside, at high temperatures, it is resistant to sulfuric acid, nitric acid, hydrochloric acid, aqua regia, neutral salts, carbon and sulfur and other erosion, 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 is extremely small.
Excellent electrical properties of quartz glass at room temperature, its resistance is equivalent to 10 times of ordinary glass, for all frequency dielectric loss is very small, a large compressive strength insulation.
Quartz glass is also resistant to cosmic radiation, nuclear fission products and non-transparent nature.
Quartz glass is mainly used for electric lighting, semiconductors, optical technology and so on.
New light: the high-pressure mercury lamp to do long-arc xenon lamp, tungsten, thallium iodide lamp, infrared lamps and germicidal lamps.
Semiconductors: the production of semiconductor materials and devices indispensable to the process material, such as the growth of germanium, silicon crucible, boat furnace core tube pan and the bell and so on.
In the field of new technologies: with its sound, light, excellent electrical performance, do the ultrasound delay line on the radar, infrared tracking direction finding, infrared photography, communication, spectrograph, spectrophotometer prism, lens , large astronomical telescope windows, high temperature window, reactors, radioactive device; rocket, missile nose cones, nozzles and radome: satellite radio insulation parts, radiation; heat scales, vacuum devices, precision casting and so on.
Quartz boat is also used for: chemical industry, metallurgy, electrical, scientific research, etc.
In the chemical industry: do high-temperature acid gas combustion, cooling and ventilation, acid solution, evaporation, absorption cooling material collection, storage devices, distilled water, hydrochloric acid, nitric acid, sulfuric acid and other preparation products, and other physical and chemical experiments. In the industry for high-temperature areas: do the optical glass, the crucible into the fluorescent kind, electric furnace core tube, gas burning radiation, and in the optics: the quartz glass and quartz glass wool can be used for rocket nozzles, heat-resistant spacecraft cover and observation windows, short, with the development of modern science and technology, quartz glass in all areas to be more widely used.
Heated areas:
Transparent quartz glass linear expansion coefficient of 5.4 * 10, equivalent to an ordinary glass 1/121/20 quartz glass as a low coefficient of thermal expansion, it is particularly good thermal stability, transparent quartz glass, the average specific heat is 0.251 (0-900 ℃) thermal conductivity is 0.0035 card / cm, sec, ° (20 ℃) transparent quartz glass deformation point, annealing point and operating temperature.
