High purity quartz is made of natural quartz by special process of crash, sorting and purification. It is mainly used in IC integrated circuit and silica glass industry, which high quality products are widely used in industries related to the long-term development of the country, such as large or super large scale integrated circuits board, optical fiber, laser, aviation，military industry and so on.
High purity quartz sand is neutral inorganic filling, which is very stable, no crystal water, no reaction with the filling material, also widely used in plastic, rubber, cementing material and coating, can increase various new functions of the product and save lots of raw materials.
Basic characteristics:
1.SiO₂：99.999%
2.Stable chemical properties: corrosion and acid resistance，low thermal expansion coefficient
Application:
1.Electronics Industry: high purity metallic silicon, communication optical fiber
2. Rubber, plastic field: used as filling, can improve the abrasive resistance
3.Coating industry: used as fillings, can improve the weather ability
4. Metallurgical industry , ceramic and fireproofing material
5.Glass industry: plate glass, float glass, optical glass, glass instrument, conductive glass, glass cloth and special glass
