Quartz rod is one of our company's superior products, specializing in the production of high-purity transparent quartz rods, and can be annealed and deep-processed. The existing specification is 0.1-80mm. The high-quality quartz rod produced by the advanced continuous melting method combined with the unique formula has good surface finish, and the bubble gas line is strictly controlled, and the bending degree does not exceed 3总. Produced by continuous melting, this transparent quartz rod has the characteristics of high purity, high temperature resistance and low coefficient of thermal expansion. The thermal expansion coefficient of the quartz rod is extremely small, only 1/10-1/20 of the glass. It has high resistance to rapid heat and cold quenching. The transparent quartz rod is heated in an electric furnace at 1100 ° C for 15 minutes, and then placed in cold water. The test will not break, the softening point temperature of the quartz rod is about 1730 ° C, the continuous use temperature is 1100-1200 ° C, and the shortest use temperature is up to 1450 ° C. Because the quartz rod has high purity, high temperature resistance and low thermal expansion coefficient. The characteristics are widely used in the pressure bridge of single-ended halogen lamps, the manufacture of fiber optic lighting, quartz fiber, the temperature measurement of polycrystalline silicon ingots in the photovoltaic industry, and the processing of semiconductor wafers.
Quartz glass is a special industrial technology glass made of silica. It is a very good basic material.

The performance of quartz glass is as follows:
1. High temperature resistance Quartz glass has a softening point of 1730 degrees Celsius and can be used for a long time at 1200 degrees Celsius. The shortest time is 1450 degrees Celsius.
2, corrosion resistance In addition to hydrofluoric acid, quartz glass is almost not chemically reflected with other acids, its acid resistance is 30 times that of ceramics, 150 times that of stainless steel, especially at high temperatures, is any other Engineering materials are unmatched.
3, good thermal stability Quartz glass has a very small expansion coefficient, can withstand severe temperature changes, the quartz glass is heated to 1100 degrees Celsius, will not burst when placed in normal temperature water
4, good light transmission Quartz glass 哎 UV to infrared has a good light transmission performance in the entire spectral band, visible light transmittance of more than 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80%.
5, good electrical insulation Quartz glass resistance value is equivalent to 10,000 times that of ordinary glass, is an excellent electrical insulation material, even at high temperatures have good electrical properties.
Quartz glass has been widely used in various fields such as electric light source, semiconductor, optical communication, military, metallurgy, building materials, chemistry, machinery, electric power, and environmental protection because of its excellent physical and chemical properties.
