Ultra-high purity quartz sand generally refers to quartz powder with SiO2 content higher than 99.99%, which is the main raw material for quartz glass and quartz crucibles. Its products are widely used in large-scale and very large-scale integrated circuits, optical fibers, solar cells, lasers, aerospace, military and other industries.

Because these industries are related to long-term development and are a necessary condition for the sustainable development of high-tech, the strategic position of high-purity quartz sand is very important. The preparation technology of its high-end products is monopolized by the United States, Germany and other countries, and technology and exports are restricted.

At present, the purification and large-scale mining of quartz sand in my country is still in a difficult stage of exploration. High-purity quartz sand has unique physical and chemical properties, especially its internal crystal structure, crystal shape and lattice change rules, which make it resistant to high temperature, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and Unique optical characteristics.

The quality requirements of quartz sand products are generally directly related to their actual industrial use. If it is used in fine and high-performance materials such as electronic materials and quartz crucibles, it has strict requirements on the quality of raw materials, requiring high-purity and ultra-pure quartz sand, and the total content of impurities should be low. Specifically, the quality requirements of quartz sand are mainly reflected in the chemical composition and particle size composition: ①The appearance is white with no visible mechanical impurities; ②Purity requirements: the content of silica is greater than 99.99%; ③According to the requirements of different industries, It can be processed into series products of different specifications and models to meet user requirements.

The above is the development status of ultra-high-purity quartz sand briefly described by the editor. You can simply understand it. The content is for your reference only, you can contact us for more inquiries.
