摘要
凹凸棒石是一种含水富镁的硅酸盐黏土矿物,具有层链状结构,结构中有着规整的孔道,是天然的一维纳米材料,其具有比表面积大、吸附性强等特点,已被广泛应用于陶瓷领域。简述了凹凸棒石的晶体结构及其基本性质,包括吸附性、催化性、填充性、胶体性和悬浮性;分析了凹凸棒石在加热过程中的结构演变过程;综述了凹凸棒石在传统陶瓷和功能陶瓷中的应用现状,并展望了其未来的研究方向。
Attapulgite is a kind of silicate clay mineral of water-rich and magnesium-rich with layered chain structure and regular pores in the structure.It is a natural one-dimensional nanomaterial with large surface area and strong adsorption,and has been widely used in the field of ceramics.The crystal structure and basic properties of attapulgite,including adsorption,catalytic,filling,colloidal and suspension,were briefly described;the structural evolution of attapulgite during heating was analyzed;The application of attapulgite in traditional ceramics and functional ceramics was reviewed,and its future research direction was prospected.
