The use of quartz instruments is very wide, in the laboratory, quartz products are widely used, quartz rod as a common quartz products with its excellent characteristics, often used. So how to judge the quality of the quartz rod?

Quartz rods are made of natural crystalline quartz (crystal or pure silica), or synthetic silane by high-temperature melting. The product after melting has good processing performance, in its high viscosity range, the tube and rod can be hot processed like ordinary glass fine work, and can also be high-speed mechanical processing with abrasive tools made of diamond or silicon carbide, 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 existence of trace impurities will greatly affect the performance of quartz glass. At the same time, due to the slight negligence of the process or thermal system, it will bring a variety of defects to the appearance quality and produce a large number of waste products. Therefore, in the application of quartz rods, the higher the purity, the better the quality.
