摘要: 在Na2O-CaO(MgO)-Al2O3-B2O3-R-H2O体系中用水热法合成了2种新型的微孔硼铝酸盐。XRD、IR和XPS分析表明,它们具有新的骨架结构。在一定温度下脱除结构中的游离水及其它分子后,所得产物表现出特征的分子筛吸附性能。吸附性能的测定结果及孔径分布的计算表明,其孔径大小在5~6Å之间。

Abstract: Two novel microporous alumino-borates were synthesized from Na2O-CaO(MgO)-Al2O3-R2O3-R-H2O systems. X-Ray diffraction analysis(XRD), IRspectra and X-Ray photo-electron spec-troscopy analyses (XPS) show that the alumino-borates have novel framework structures. They exhibit charateristic adsoption properties like that of zeolite after the desorption of free water and other molecules within their structures. It is also shown that the micropore size of the alumino-borates are between 5~6Å.
