摘　　要：高纯石英物理化学性能优异,应用广泛,是新一代信息产业、新能源、新材料等战略性新兴产业必不可少的关键基础材料。全球高纯石英资源稀少,主要集中在美国、挪威、俄罗斯、印度等国家,我国4N5级(SiO_(2)含量>99.995%)及以上高纯石英矿石原料基本依赖进口。目前国内高端高纯石英产能有限,供不应求,未来随着光伏、半导体等领域需求的迅速扩张,预计到2025年我国4N(SiO_(2)含量>99.99%)级及以上高纯石英需求将快速增长到38万t,高纯石英资源供给安全问题突出。通过全面分析全球高纯石英资源现状、市场供需现状、主要生产企业以及消费趋势,结合我国高纯石英产业现状,提出了将高纯石英矿产列入战略性矿产、加强高纯石英战略研究和科技攻关、建立全链条评价体系等对策建议,以保障我国高纯石英资源供给安全。High purity quartz(HPQ),as an indispensable key basic material,has been widely used in strategic emerging industries including the new-generation information industry,new energy,new materials,etc.,due to its superior physicochemical properties.However,HPQ resources are scarce and concentrated in countries such as the United States,Norway,Russia,and India.In China,4N5 grade HPQ(SiO_(2)content≥99.995%)is primarily dependent on imports.At present,the domestic production capacity of high grade HPQ is limited and the demand exceeds the supply.In the future,it is expected that China's demand for 4N grade HPQ(SiO_(2)content>99.99%)will grow rapidly to 380000 t by 2025 with the rapid expansion of demand in the photovoltaic and semiconductor industries.As a result,the supply security of HPQ resources will be prominent.The current situation of global HPQ resources,current market supply and demand,major producers as well as consumption trends were comprehensively analysed.Furthermore,the countermeasures were proposed,including HPQ minerals as strategic minerals,strengthening strategic and scientific research on HPQ,and establishing a whole-chain evaluation system,based on the current situation of China's HPQ industry.These would be of great value in ensuring the security of HPQ supply in China.
