Composition and Application of Quartz boat

Quartz boat is made from silica-containing substances, including crystals, silica, and silicon tetroxide as raw materials by high-temperatures melting. With excellent optical properties, it has particularly good light transmission from ultraviolet to infrared. In addition, it is highly acid-resistant, and at high temperatures, it can withstand the corrosion of sulphuric acid, nitric acid, hydrochloric acid, aqua regia, neutral salts, carbon, and sulfur, etc.. Its chemical resistance is 30 times that of acid-resistant ceramics and 150 times that of nichrome and ceramics. It is also resistant to high temperatures, thermal shock, and has a very low coefficient of thermal expansion.

In the context of new light source applications, the quartz boat can be utilised in the production of a range of devices, including high-pressure mercury-vapor lamps, xenon long-arc lamps, iodine tungsten lamps, thallium iodide lamps, infrared lamps, and germicidal lamps. In the field of semiconductor applications, the quartz boat is a crucial component in the manufacturing of semiconductor materials and devices. This includes the crucibles used for growing germanium and single silicon crystals, core tubes of boat furnaces, and bell jars.

In the field of new technology, the acoustic, optical and electrical properties of this material can be exploited for a variety of applications, including the fabrication of ultrasonic delay lines for use in radar, infrared tracking, infrared photography, communication systems, spectrographs, spectrophotometers, prisms, lenses, reflecting windows for large astronomical telescopes, high temperature operating windows, reactors and radioactive devices. Additionally, this material can be used in nose cones, nozzles and radomes for rockets and missiles, as well as in radio-insulating parts for satellites, thermobalances, vacuum adsorption devices, precision casting and other similar applications.

Quartz boat is also used in: chemical industry, metallurgy, electrical, scientific research and other aspects.

In the chemical industry, it can be employed for the apparatus of acid gases combustion at high temperatures, cooling and ventilation, the evaporation of acidic solutions, the construction of devices for the collection and storage of cooling suction and distilled water, the preparation devices of hydrochloric acid, nitric acid, sulfuric acid, and other chemical and physical experiments. In high-temperature operations, it can be employed for the fabrication of optical glass, crucibles, core tubes of electric furnaces, and gas combustion radiators. From an optical perspective, quartz glass and quartz glass wool can be employed in the construction of rocket nozzles, heat shields and observation windows for spacecraft.

As a consequence of the advancement of contemporary scientific and technological knowledge, quartz boats have become more prevalent in a range of applications. This has been accompanied by a corresponding increase in demand.
