Quartz glass is a good acid resistant material, except for hydrofluoric acid andIn addition to hot phosphoric acid above 300 degrees, it can withstand corrosion from sulfuric acid, nitric acid, hydrochloric acid, aqua regia, neutral salts, carbon, and sulfur at high temperatures. Its chemical stability is equivalent to 30 times that of acid resistant ceramics and 150 times that of nickel chromium alloys and ceramics. It is resistant to high temperatures, thermal shock, and has a particularly small coefficient of thermal expansion.

The electrical properties of quartz glass, at room temperature, have a resistance equivalent to 10 times that of ordinary glass, with minimal dielectric loss at all frequencies and high insulation and voltage resistance strength.

Quartz glass also has the properties of being resistant to cosmic radiation and impermeable to nuclear fission products.

Quartz glass is mainly used in electric light sources, semiconductors, optical new technologies, and other fields.

In terms of new light sources, we specialize in high-pressure mercury lamps, long arc xenon lamps, iodine tungsten lamps, thallium iodide lamps, infrared lamps, and sterilization lamps.

In terms of semiconductors, they are materials used in the production process of semiconductor materials and devices, such as crucibles for growing germanium and silicon single crystals, boat furnace core tubes, and bell jars.

In the field of new technology: using its acoustic, optical, and electrical properties to create ultrasonic delay lines on radar, infrared tracking and direction finding, prisms for infrared photography, communication, spectrometers, spectrophotometers, lenses, reflection windows for large astronomical telescopes, high-temperature operation windows, reactors, and radiation devices; Rocket and missile nose cones, nozzles, and antenna covers: radio insulation components for artificial satellites, radiation; Hot scale, vacuum adsorption device, precision casting, etc.

In terms of high-temperature industry, it can be used as optical glass, crucible as fluorescent material, electric furnace core tube, gas combustion radiator. In terms of optics, quartz glass and quartz glass wool can be used as rocket nozzles, spacecraft heat shields and observation windows. In short, with the development of modern science and technology, quartz glass has been widely used in various fields.

Heating aspect:

The coefficient of linear expansion of transparent quartz glass5.4 * 10, equivalent to 1/121/20 of ordinary glass. Due to the low coefficient of thermal expansion of quartz glass, its thermal stability is particularly good. The average specific heat of transparent quartz glass is 0.251 (0-900 ℃), and the thermal conductivity is 0.0035 kcal/cm, s, and degrees (20 ℃).
