摘　　要：高岭土是一种天然的黏土矿物,具有典型的1:1层状硅酸盐晶体结构。首先介绍了高岭土资源背景、结构组成和物化特性,着重介绍了高岭土在节能环保、生物医药和新材料三个战略性新兴产业的研究现状。天然的层状结构、丰富的表面羟基、较大的比表面积以及良好的生物相容性为高岭土的功能化应用提供了多种选择。随着科学技术的发展和国家社会的进步,对高岭土的研究更加深入。未来高岭土将作为一种战略性非金属矿物,在更多的领域有更好的应用前景。Kaolin is a natural clay mineral with a typical 1:1 layered silicate crystal structure. This paper firstly introduces the background, composition and physicochemical characteristics of kaolinite resources, and emphatically introduces the research status of kaolinite in three strategic emerging industries of energy conservation and environmental protection, biomedicine and new materials. The natural layered structure, abundant surface hydroxyl groups, large specific surface area and good biocompatibility provide a variety of options for the functional application of kaolin. With the development of science and technology and the progress of national society, the research on kaolinite will be more in-depth.Kaolin will be a strategic non-metallic mineral in the future and will have better application prospects in more fields.
