【摘要】：电气石是非金属矿物领域中较为重要的一类硅酸盐类矿物,属非可再生类天然矿物。电气石晶体具有化学成分复杂、晶形及颜色多样等特征。电气石晶体内部的物质及结构特征,使其具有压电性、热释电性、自发极化效应和释放负离子等特性。近年来,关于利用电气石的环境功能属性制备各类复合功能材料的研究已成为备受关注的热点。基于电气石的来源、分类、晶体内部物质成分与结构组成等,概述了电气石的理化结构特征及各环境功能属性,进而论述电气石及其复合功能材料在各个实际领域中的应用,归纳并总结电气石在现今环境污染治理应用当中存在的相关问题,最后对电气石及其复合功能材料的发展前景进行了展望。
[Abstract]:Tourmaline is an important class of silicate minerals in the field of non-metallic minerals, which belongs to non-renewable natural minerals. Tourmaline crystals are characterized by complex chemical composition, crystal shape and various colors. The physical and structural characteristics of tourmaline crystal make it have piezoelectric, pyroelectric, spontaneous polarization effect and release of negative ions. In recent years, the research on the preparation of various composite functional materials using tourmaline's environmental functional properties has become a hot spot. Based on the source, classification, material composition and structure composition of tourmaline, the physical and chemical structure characteristics and environmental functional properties of tourmaline are summarized, and the applications of tourmaline and its composite functional materials in various practical fields are discussed. The problems existing in the application of tourmaline in environmental pollution control are summarized and the prospect of tourmaline and its composite functional materials is prospected.
