Quartz tube must be unfamiliar with it, quartz tube has a very low coefficient of thermal expansion, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, the best through the UV Spectral properties and visible and near-infrared spectral properties, and has a higher than ordinary glass mechanical properties. Therefore, it is one of the indispensable excellent materials in modern technology, such as space technology, atomic energy industry, defense equipment, automation system, and semiconductor, metallurgy, chemical industry, electric light source, communication, light industry, building materials and so on.

The quartz tube is made of natural crystalline quartz (crystal or pure silica), or synthetic silane is melted by high temperature to form quartz glass. After melting the product has excellent processing performance, in a very high viscosity range, the tube and rod can be the same as the ordinary glass of the same thermal processing, can also be made of diamond or silicon carbide abrasive for high-speed machinery Processing, quartz glass heater to produce a variety of complex shapes of instruments and special products. The performance of quartz glass depends mainly on its purity, followed by the process or thermal system. The presence of trace impurities will have a significant impact on the performance of the quartz glass; at the same time, due to the slight negligence of the process or thermal system, the quality of the appearance will bring a variety of defects, resulting in a large number of waste products.
