Review for High-purity Quartz (SiO2) (Part Ⅲ): Analysis, Activation and Separation of Fluid Inclusions
-
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。流体包裹体，一种来源于原生成矿流体，或是在后期地质作用中被石英捕获的流体，是石英中典型的流体杂质；特别是一些被包裹于石英晶体中的微小气、液包裹体，很难有效地被常规的选矿技术分离。本文详细地阐述了高纯石英中流体包裹体的基本特性，对流体包裹体的活化与分离技术现状进行概述；基于近年来我国高纯石英基础理论研究进展，并对我国高纯石英基础理论研究提出科学建议。
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. Fluid inclusions, either derived from primary ore-forming fluids or captured by quartz in late geological actions, are typical fluid impurities in crystal quartz. In particular, some small gas and liquid inclusions encapsulated in quartz crystals are difficult to be separated effectively by conventional mineral processing techniques. In this paper, the basic characteristics of fluid inclusions in high purity quartz are described in detail, and the current status of fluid inclusions activation and separation technology is summarized. Based on the research progress of the basic theory of high-purity quartz in China in recent years, some scientific suggestions on the basic theory of high-purity quartz in China are put forward.
