Abstract:High purity quartz is raw materials of high-grade quartz products and the material basis of the high-end products of silicon industry,which are widely used in photovoltaic, electronic information, electric light source and optical communications industry.It has an important position and role in the new energy and new materials in emerging industries.This paper introduces the application status of the domestic high pure quartz sand in recent years and purification of quartz sand processing mainly, were reviewed the domestic development and progress of high pure quartz sand technology in recent years.Especially in the field of deep processing, quartz sand is required to develop in the direction of high purity, low crystallinity, low radioactivity and sphericity.Therefore, it is of great significance for the future development of science and technology to master quartz sand purification and deep processing technology.
