【摘要】 高纯石英著以杂质极少、纯度极高，现已广泛地应用于光纤通信、光伏、航空航天、半导体显示等高新技术产业。广泛赋存于石英晶体结构中的微量金属、非金属元素（H、Li、B、Na、Al、P、K、Ca、Fe、Ti等）因被Si-O-Si键紧密束缚而难以被常规的选矿技术分离。本文详细地阐述了高纯石英中被晶格束缚的微量元素赋存机制，并对国际上高品质石英晶体结构中的微量元素的先进分离技术进行了全面、系统地概述；基于近年来我国高纯石英基础理论研究进展，对我国高纯石英晶格杂质分离的基础理论研究提出合理化的科学建议。更多还原

【Abstract】 High-purity quartz, famous for low impurities and high purity, has been widely used in optical fiber communication, photovoltaic, aerospace, semiconductor display and other high-tech industries. The trace metal and nonmetallic elements(H, Li, B, Na, Al, P, K, Ca, Fe, Ti, etc.) widely occurring in quartz crystal structure are closely bound by Si-O-Si bond, which is difficult to be separated by conventional mineral processing technology. In this paper, the occurrence mechanism of trace elements bound by lattice in high-purity quartz is described in detail, and the advanced separation technology of trace elements in the crystal structure of high-quality quartz in the world is comprehensively and systematically summarized.Based on the research progress of the basic theory of high-purity quartz in China in recent years, some reasonable scientific suggestions on the basic theory of impurity separation of high-purity quartz lattice in China are put forward.更多还原
