摘　　要：以钠基累托土为原料制备了铝层柱累托土,采用XRD和TEM进行表征,并研究铝层柱累托土的水热稳定性。研究表明,铝层柱累托土经100%水蒸汽800℃水热处理10 h后,片层结构依然保持完好,具有较高的水热稳定性,但比表面积和孔容均较低。A1-Rectorites were prepared using sodium rectorite as the raw material and characterized by X-ray diffraction and transmission electron mierographs. The water thermal stability of Al-rectorites was investigated. The results revealed that Al-rectorite could still remain high water thermal stability and good laminated structure after hydrothermal treatment at 800 ℃ for 10 h with 100% aqueous vapour, but its pore volume and surface area were not large enough.
