摘　　要：高纯石英砂是高档石英制品的原材料,是硅产业高端产品的物质基础,其广泛运用于光伏、电子信息、电光源和光通讯等行业,在新材料新能源等战略性新兴产业中具有重要地位和作用。本文阐述了近几年国内高纯石英砂的应用现状及主要的提纯石英砂的选矿工艺,综合评述了深加工领域中石英砂向高纯度、低结晶度、低放射性、球形化等方向发展的趋势,阐明了石英砂提纯及深加工技术对科技发展的重要性。High purity quartz is raw materials of high-grade quartz products and the material basis of the highend 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 the main processing technology for purification of quartz sand. In the field of deep processing,quartz sand is required to develop in the direction of high purity,low crystallinity,low radioactivity and sphericity. The importance of quartz sand purification and deep processing technology for development of science and technology is pointed out.
