Information

Quartz glass has a very low thermal expansion coefficient, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, the best UV-transmitting spectrum performance and visible light and near-infrared spectrum transmission Performance, and has higher mechanical properties than ordinary glass. Therefore, it is one of the indispensable and excellent materials in modern cutting-edge technology in space technology, atomic energy industry, national defense equipment, automation system, and semiconductor, metallurgy, chemical industry, electric light source, communications, light industry, building materials and other industries.

 

Quartz glass is made of natural crystalline quartz (crystal or pure silica) or synthetic silane at high temperature. The molten product has excellent processing performance. In the extremely high viscosity range, the tube and rod can be hot processed like ordinary glass fine work, and the abrasive tool made of diamond or silicon carbide can be used for high-speed machinery. Processing, so as to make a variety of complex shapes of instruments and special products. The performance of quartz glass mainly depends 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 a slight negligence in the process or thermal system, it will bring a variety of defects to the appearance and quality, resulting in a large number of waste products.
