The variety and use of quartz glass are closely related. Users require the production of the quartz glass they need based on the characteristics of quartz glass, resulting in the variety of quartz glass. The new variety has improved the performance and quality of quartz glass, promoting the development of the quartz glass industry. Almost all industries use quartz glass, but due to the complex process of quartz glass products and the high cost of raw materials, the price of quartz glass is also high, which limits its widespread use. Here is a brief introduction to the main varieties and uses of quartz glass.
Transparent quartz glass is widely used in electric light sources such as mercury lamps, ultra-high pressure mercury lamps, xenon lamps, ultraviolet lamps, iodine tungsten lamps, halogen lamps, gas laser lamps, metal halide lamps, etc. due to its excellent light transmittance and heat resistance from the ultraviolet to infrared regions. It is the largest user of quartz glass in China.
Transparent quartz glass is extremely pure SiO2 with almost no impurities. It is an indispensable material for the semiconductor industry in crucibles and tubes for silicon, crucibles for potassium alloys, and other high-purity metal manufacturing devices. The main varieties include large-sized quartz glass bell covers (outer covers for manufacturing polycrystalline silicon furnaces). In the past, impermeable steel was used, which affected product quality. Moreover, the furnace shell needs to be cooled by water. Now, it has been changed to quartz glass bell covers, which do not require water cooling. This not only saves energy but also improves the quality of polycrystalline silicon; Using polycrystalline silicon to produce monocrystalline silicon requires a large amount of quartz glass crucibles, which are essential materials and cannot be replaced by other materials; When manufacturing integrated circuits and transistors using silicon single crystals, processes such as epitaxy, impurity expansion, and sintering are carried out in quartz glass expansion tubes or quartz glass bell covers; In addition, quartz glass supports should also be used to clean silicon wafers; So the semiconductor industry requires a large amount of use of various specifications of quartz glass tubes, quartz rods, quartz crucibles, and quartz glass instruments and vessels.
Using opaque quartz glass (milky white quartz glass) to manufacture infrared heaters, heaters, crystal heaters, etc., consumes nearly a thousand tons of milky white quartz glass tubes annually. Mainly used for heating electroplating solutions, acid heating, household heating, tempered glass heating, industrial paint baking (bicycles, cars, etc.), and food, paper, textile industries.
The conductivity of quartz glass tube is essentially ionic, while alkali metal ions only exist in trace amounts, so it has excellent electrical insulation and low dielectric loss. The main feature of quartz glass is good electrical performance at high temperature, so it is used in missiles and space technology technology.
