The xiaobian of Jiangsu Jingrui Quartz Industry Development Institute Co.,Ltd. the application fields  main uses of high purity quartz sand to you. High purity quartz sand generally refers to quartz powder with SiO2 content higher than 99.9%. It is the main raw material of quartz glass  quartz crucible. Its high-grade products are widely used in large-scale integrated circuits, solar cells, optical fibers, lasers, aerospace, military  other industries. High purity quartz sand has excellent chemical stability, high insulation pressure resistance  very low volume expansion coefficient. It is an indispensable  important raw material for electronic core devices, optical communication materials, solar cells  other high-tech industries. It is also the basic raw material for quartz crucible production, monocrystallyte silicon rod containers  chips.

High purity quartz sand is the main raw material of quartz glass. Quartz glass is called "king of glass" because it has a series of special physical  chemical properties.

High temperature resistance. It has excellent high temperature resistance, temperature resistance as high as 1100 ~ 1200℃, 800℃ higher than ordinary glass, its melting point  platinum (platinum) melting point similar. The average coefficient of thermal expansion between 0  1000℃ a = 5.4×10-7, equivalent to 1/6 of ceramic, equivalent to 1/20 of ordinary glass, quartz glass mixed with a certain amount of titanium, can be inhibited into ultra-low expansion quartz glass with expansion coefficient close to zero.

Excellent spectral characteristics. Quartz glass has excellent spectral characteristics,  only through visible light, but also through infrared, ultraviolet. Quartz glass is a good acid resistant material, equivalent to acid resistant ceramics 30 times, equivalent to stainless steel (nickel chromium alloy) 150 times.
