摘　　要：累托石为二八面体云母和二八面体蒙脱石组成的1∶1型规则间层矿物,是一种具有特殊结构的粘土矿物,具有热稳定、耐高温、吸附、阳离子交换、高分散、高塑、阻隔紫外线、层间孔径可变和结构层分离等独特的物理性质。我国累托石粘土主要赋存于二叠系地层中,表现为沉积—成岩建造与岩浆热液建造两种成因模式。目前,累托石已广泛应用于环保材料、高温润滑脂、纳米材料等众多领域,并取得了较大突破,但是无论从广度和深度上均有待进一步扩展。The rectorite is the regularly interstratified mineral ofdioctahedral mica and dioctahedral montmorillonite in a 1：1 ratio. It has a series of particular physical properties such as thermal stability, heat-resisting quality, adsorbability, cations exchangeability, good dispersibility, high plasticity, barrier of ultraviolet ray, changeable pore diameter of interlayer, dissociable layer and etc. At present, the rectorite has been widely used in eco-friendly materials, high temperature grease, nano-materials, and many other fields. Although the application of rectorite has made great breakthroughs, the breadth and depth need to be further extended.
